Graphical Errors in 5.15.0 (DO NOT UPDATE YET!)

[ArceusI]

Seriously...This is screwed up...

I just updated to 5.15.0, this is horrible. Was this even playtested with every single game & mod?
This is inexcusable for a game that tries to be consistent with Minecraft. I'd rather downgrade to 5.14.0 and remain there indefinitely until this gets resolved. Was it something to do with an unforseen consequence of a particular section of the update?

Nobody here owes you anything.

With a post like that, don't be surprised if nobody is willing to help you.

Well, I downgraded back to 5.14.0, I'm not going up to 5.15.0 till these graphical errors are corrected. This is rather serious.

[freshreplicant]

I can't really figure out what's going on in the screenshot, or what it's meant to look like. Would you mind explaining what the errors are?

[Nininik]

I dont understand the screenshot and for me everything is fine on my end- What issue is this exactly showing?

I thought that 5.15.0 would work fine, but when I started my typical MineClonia world with a bunch of mods, the graphics were messed up seriously, and some blocks textured incorrectly. Likely had something to do with Luanti itself, because it didn't happen in 5.14.0, I blame the developers of Luanti for this blunder. So I refuse to upgrade till the glitch is resolved.

It would be helpful to have a screenshot of the same scene in both 5.14.0 and 5.15.0 to demonstrate the difference

Please remember that the developers are volunteers, it's unproductive to play the blame game and act entitled

Oh...Shoot...Well, I did play MineTest in 5.14.0 and didn't run into graphical issues, with exceptions for mod texture glitches, particularly Unbreaking in MineClonia, which creates dummy textures. But not the corrupted textures as shown in the screenshot for 5.15.0.

This is what it's supposed to look like (5.14.0)

I did manage to snap a screenshot of MineClonia in 5.14.0, so now you guys can compare them, the grass blocks were one such block that was affected, and it's seemingly random in nature.

Try the setting video_driver = opengl. If that does not help or you don't know how, please provide

1. a screenshot from 5.15.0
2. a screenshot from 5.14.0 of the same scene as for 5.15.0
3. your system details, most importantly OS, GPU name and drivers versions

Without having all of these points satisfied, there is little to no way of helping you.

Well, unfortunately, there's practically nothing I can do, because I refuse to go to 5.15.0 until the graphical glitches are resolved. I found it within 24 hours of the updates release. Yet, none of you care about it, I know Mojang would never let such graphical glitches fester, which is why every release of Minecraft lacks any significant graphical glitches. Consider me as "Staying behind" in this case.
Making matters worse: Android doesn't permit downgrading applications, so I was forced to uninstall the application, which resets it, and nothing was left. So it's more difficult to send screenshots from 2 different versions if I refuse to go forward. Maybe somebody else ran across it, and I hope they supply the screenshots to prove my point.

Tip: If nobody else has the issue or cannot reproduce it, then it won't get fixed. It might take a while until someone reports this issue who has exactly the same hardware, OS and configuration as you.

Also yes - not being able to downgrade apps on Android is also something I very much dislike.

I just showed the glitch to F-Droid, and they are legitimately shocked that such a glitch exists in Luanti. So F-Droid could revert back to 5.14.0, which would lead to a version dispute.

Look, I know this is frustrating. But in effect you're refusing to get yourself help, because you're the only one has both (1) experienced this glitch and (2) reported it. We do care, however you can't expect us to fix an issue that we can't reproduce or on which we simply don't have enough information. We are all on different computers and phones, on different operating systems (such as Android versions).

Mojang is a multi-dollar company who can test their game on all the hardware they want it to run on. Luanti is a volunteer project where the community are invited to test things, but there is never any guarantee. It's absurd to compare the two.

Making matters worse: Android doesn't permit downgrading applications, so I was forced to uninstall the application, which resets it, and nothing was left.

I'm sorry you lost your data. It's quite bad that Android won't let you gracefully downgrade, and the files can't be touched by other apps usually. It is all up to you what to do. Consider though, that since you already are starting from scratch, maybe pushing harder to get the bug fixed by providing more data is not so bad an option. Have you got much to lose? Well, if it's going to make you lose your temper, then that's fine, leave it be.

That would be pretty drastic. I have 5.15 installed through F-Droid and no problems with it.

We do test but none us has seen this issue (I'm not even sure what you're referring to - is it the textures looking odd or the unshaded appearance?)

Here's what Mineclonia looks like to me on Luanti 5.15, for example:



Devices vary a huge amount, knowing literally any information about your device, the mods you're using, any modified settings, and the difference between expected/unexpected would make a huge difference and actually allow us to look into this issue

[Nininik]

My friend on a Motorola reported having MAJOR FPS DROPS when he press any button and somehow it "dosent lag when he records"

android (unless the manufacturer disables it) has a "performance mode" which turns on when a foreground app is usig unusual amount of resources (ex. cpu, ram, battery etc). my tab even turns the ips panel to 90hz mode even if i turn that option completely off. i would guess that the screen recording triggered the performance mode, while the game wasnt enough heavy for that. (according to my best knowledge)

Making matters worse: Android doesn't permit downgrading applications, so I was forced to uninstall the application, which resets it, and nothing was left.

if you are between android 11 and 14 you can use 'install-with-options' app from f-droid to downgrade anything. you can even access the android data folder, and the luanti game files that way. i did downgrade luanti multiple times, even on heavily restricted versions of android.

I don't see where in this thread:

https://forum.f-droid.org/t/luanti-isnt ... tory/33957

the "legitimate surprise" or abhorrence which you impute to F-Droid is expressed. Please don't misrepresent the facts and the measures you have taken. All that accomplishes is to disincentivize others to assist you.

Freshreplicant and Nininick said that too, I thought they were trolling this "Karen"... To me at the very least, the yellow-blocks-with-leaves blocks in the first screenshot look like a transparency issue. It's the kind of thing I got when the use_texture_alpha attribute was changed at some point. The violet blocks in the back and the wood-on-blue-background on the right seem out-of-place too. In this cases, it looks "as if" the wrong textures are being applied - which is consistent with the first case (texture with alpha channel being used in a block definition without use-texture-alpha).

[rubenwardy]

If the problem is the wrong textures being displayed, then is this fixed if you go to Settings > Enable advanced settings > Search for array_texture_max > set to 0 ?

I hope that you're young and just don't know any better, but you're being very unfair here.

Within two days of your post, on a weekend no less, you have multiple Luanti core developers and maintainers, who are unpaid volunteers, trying to help you and asking you for useful details that would help pinpoint the issue, and you have not so far provided anything beyond a single vague screenshot and the fact that you installed Luanti 5.15. They are doing this despite you falsely claiming on the FDroid forums that nobody cares and that nobody is helping you.

Your posts are missing lots of important details that would provide valuable information to the many people in this thread trying to help you and also maybe squash a bug in the project we all care a lot about.

These questions could be answered without you reinstalling 5.15, which you've already said you won't.

The questions are:

1. What version of Android are you using?

2. What is the model and brand of your phone?

3. What game were you playing when this issue occured? What version was the game you had installed - .e.g. not the version of Luanti, the launcher/engine, but the actual game you got from ContentDB and ran into this issue with?

4. Was the world you saw these issues in created in an earlier version of Luanti?

5. Are you using any mods, if so, what mods? Are any of the blocks that are rendering wrong from a particular mod or are they base game blocks?

For an example of how to provide these details when making a bug report: to see if I could reproduce your issue, I downloaded Luanti on my Xiaomi Redmi Note 10 5G, which is running Android 13 and MIUI Version 14.0.4, installed the newest version of Minetest game from ContentDB (which was released on 2025-12-10). I created several worlds using V7 mapgen so that I could see all the base game biomes and walked around for 1-3 minutes and could not reproduce any of the issues in your first screenshot.

That suggests that there is something happening related to how Luanti works on either your version of Android, the version of the game you are playing, the mods you are using, or a combination of all of these. That makes is hard to reproduce and debug. That doesn't make your issue invalid at all, it just means the people trying to help you need more details to figure out what's going wrong so they can fix it.

If you provide those details, then these helpful people can ensure that this two day old issue does not 'fester' as you put it, and thereby ensure that nobody else has to run into it like you did.

Freshreplicant and Nininick said that too, I thought they were trolling this "Karen"

For the record, I was not trolling, Luanti offers so many games and mods, some of which have some pretty crazy and garish visuals, often with their own quirks and glitches, so it's just very hard to decipher the screenshot, like what game is being played, what mods are installed (if any) and what things are meant to look like. Plus there's so much user freedom to add further conent and even their own mods, so you really need more details to narrow things down.

[freshreplicant]

I looked at the FDroid thread, and I noticed you mentioned one of the two devices you tested it on is a Boost Summit 5G.

I was not familiar with the make of phone, so here is the details of the phone, in case it helps anyone narrow it down:

Actually...I think it has something to do with Mods...When I add certain mods to any game on Luanti 5.15.0, it freaks out and glitches the graphics, still a very severe issue, but again, it's hard to test considering there's over 2,000 mods!

[Linuxdirk]

So you installed over 2000 mods while running a “specialized” game and complain about issues?

And not only that, but also in a very disrespecting and aggressive way.

… and you kept your 2000+ mods setup secret until being already 20 replies deep into this thread?

That’s wild.

[freshreplicant]

over 2,000 mods!

...wow...that...is a very important detail.

I really think you owe the devs and people who tried to help you an apology, and you should probably clarify that it was down to your specific 2,000 mod setup and not some huge issue in Luanti in the F-Droid thread. The thread where you claimed: that the developers "refused to do anything" and called it a 'graphical nightmare across the entire platform'...when only YOU have so far encountered it, with, again, 2,000 mods installed.

I'm surprised quite frankly your phone and tablet haven't burst into flames with what you're putting it through.

After you've done that, please maybe watch something like this on how to report a bug and put it into practice next time you want to report an issue: https://www.youtube.com/watch?v=Qqfbr2itLGM

No, I was noting how many mods are available, I don't download that many mods, only specific ones for my needs. Somehow, one of them caused this issue, or probably a couple of them. I know none of ApolloX's mods are the culprit...That still raises the question: What in tarnation is causing these graphical glitches? I did upload two more screenshots over on F-Droid Forums, and they confirmed that it is a serious graphical glitch. However, the hunt is on to find the culprit(s) of these glitched textures, so I'm changing the Subject officially to a General Mod glitch, but still, it's rather serious, and the mods that cause it should be fixed immediately or get axed from Luanti indefinitely to avoid these glitches.
Though, I do humbly apologize for making a rushed assumption. I thought Luanti itself was the cause, but it looks like some mods may be causing this issue outright.
