Release Type: Official Release

Version: 4.1.0.1805+

Platform(s): Linux, Fedora

Describe the bug

It is not possible to play any 3D game during runtime because of error : Error while compiling GLSL shader. [] using Wayland driver

To Reproduce
Steps to reproduce the behavior:

1. Run GameStudio
2. Create new project based on SpaceEscape template
3. Add Linux platform
4. Go to Linux platform project and build It to test executable on Linux
5. Run

Expected behavior
The application should work flawlessly

Additional context
Described bug exists only for Wayland. If you switch to X11 by setting following variable

export SDL_VIDEODRIVER=x11

then problem does not occur.

I found another way to reproduce the error:

1. create a project from an empty template - select HDR and Level 11
2. remove skybox and leave only two elements for Main Scene - camera and light.
3. import any custom model (for testing purposes I used royality free Train kit from Kenney).

Another use case:

1 . create a project from an empty template
2. remove skybox and leave only two elements for Main Scene - camera and light.

3. this time import only spritesheet (download any image from the internet or create by yourself) and add it to the scene

Works

Conclusion : Both Procedural and Imported models may share a common code that is flawed

Edit: Error occurs for MeshRenderFeature

[Jklawreszuk]

Okay...That's new.

Another use case
1 . create a project from an empty template, but this time don't check the HDR option and use LDR instead - also pick lowest API level - Level 9
2. remove skybox and leave only two elements for Main Scene - camera and light.
3. import any model - procedural cube for example

Works!

Those steps sound like a similar issue to the mobile issue steps #2485

You might be able to just uncheck Generate mipmaps if Im right? I dont know how much that info actually helps you but if its true it may be useful.

I'm not sure if this is the case because my test projects don't contain any materials at all 😕

[Jklawreszuk]

I compared the shader scripts and on both Windows and Linux they are the same
Edit: Only difference I didn't noticed is GL.CreateProgram return 0. Also, SDL.MakeCurrent fails...

[Jklawreszuk]

Another progress, I was able to capture SDL error:

INFO: Unable to make EGL context current (call to eglMakeCurrent failed, reporting an error of EGL_BAD_ACCESS) -1

[Jklawreszuk]

Huh...Good news ! Looks like I have managed to making it work!
Bad news is that there is something wrong with wayland
Setting following env variable to X11 fixed an issue:

export SDL_VIDEODRIVER=x11
