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.

Screen_Recording_20220607-150240_Farming.Game.mp4

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...

godot/platform/android/display_server_android.cpp

Line 522 in 4bbe7f0

ERR_FAIL_NULL(native_window);

[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:

godot/platform/android/display_server_android.cpp

Line 492 in 4bbe7f0

rendering_driver = "vulkan";

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 #84852 Which will be part of 4.2.1. Once 4.2.1, please test again and confirm

Can anyone reproduce this in 4.2.1 or later?
