Issue description

I'm working on little farming game. I played the game on my android phone, and I see that the tilemaps render incorrectly and look extremely weird.

Sometimes the game runs normal without any glitches, other times it looks extremely weird.

Steps to reproduce

1. Download the project below.
2. Open it up in godot 4
3. Run it on your android device

Minimal reproduction project

Since my game is very small and I plan to open source it anyway. You can download it here.

Can you reproduce this after switching to the OpenGL rendering backend in the Project Settings?

@Calinou, I changed rendering/driver/driver_name to opengl3. Exported the game to my phone via USB debugging. I got this error message:

No idea why it's talking about Vulkan when I'm not even using it in this case.

Same error with 4.0-dev alpha 10, switched to GLES3 backend and appears same message in Android. I have a Redmi 9T and have GLES3 drivers on Adreno GPU. @Dan-Gamin did you solve this?

[Alexia-AT-Digitecnology]

I'm seeing the source code and seems the gles3 backend is not compiled...

https://github.com/godotengine/godot/blob/4bbe7f0b98de72d6dd77d5ade4b761de375bcf66/platform/android/display_server_android.cpp#L522

[Alexia-AT-Digitecnology]

Did you have set in the buildserver the GLES3_ENABLED option in android export template @Calinou? Do you use Azure Pipelines to deploy the builds?

[akien-mga]

Vulkan is hardcoded here, GLES3 can't be used yet: https://github.com/godotengine/godot/blob/4bbe7f0b98de72d6dd77d5ade4b761de375bcf66/platform/android/display_server_android.cpp#L492

Edit: This was fixed by #69355.

I had the same issue. I was able to switch the renderer to gl_compatibility in Godot 4.0.beta10 and that fixes it.

[giulong]

had the same issue on Android export using Godot 4.0.2.stable. Disabling Use Texture Padding in the TileSet atlas properties as suggested in this comment by @Calinou fixes it.

This was likely fixed by https://github.com/godotengine/godot/pull/84852 Which will be part of 4.2.1. Once 4.2.1, please test again and confirm

[clayjohn]

Can anyone reproduce this in 4.2.1 or later?
