"Lake" stone textures are stretched with Vulkan

• System information from steam: https://justpaste.it/1qy6t
• Have you checked for system updates?: Yes

Please describe your issue in as much detail as possible:

On the wingman map "Lake", the texture of stones are wrongly stretched.

Steps for reproducing this issue:

1. start CS:GO with -vulkan
2. load a wingman game with Lake

@christianrauch could you revalidate your files and maybe if this doesn't work you have the option to try a wayland session. I can't reproduce it.

I verified the files via Steam but I am still facing this issue. Removing the -vulkan flag from the start options switches back to OpenGL and the stones appear with the correct texture again. In the direct comparison of the "Lake" map with OpenGL and Vulkan, I noticed that with OpenGL the scene is much darker than on Vulkan. There is definitely something different when running on OpenGL and Vulkan and the shaders just behave differently.

I am already on Wayland. But since steam does not support Wayland yet, this is all just running via XWayland. Is there an option to run Steam via Wayland?

For reference, I am using an Intel iGPU:

@christianrauch currently there is no working way to use steam via Wayland only.

I can not tell you if this is maybe a driver issue or if this is a bug in CSGO. Maybe someone with UHD GPU can retest this.

The only thing where I'm always cautious is when using experimental / latest technologies and trying to get this working on old LTS versions. But maybe we will get someone to test this.

i also have the same issue on Intel HD 620 too (X11 session)
