Symptoms

  1. When the Bloom effect is on, small blue squares appear all over the screen
    2024-03-02_17-43-23

a lot of little squares (video)
[Bloom is turned on at the beginning of the video - there are artifacts in the kind of blue squares spontaneously appearing all over the screen, then I turn off Bloom, the squares disappear, at the end I turn it on, the squares appear]
[Sorry I can't switch the language in the game settings, regional restrictions]

  1. Minimap extends beyond the boundary of the circle and overlaps the player counter

    It should be like this:

Reproduction

Run game using proton on amd gpu
(I had an Nvidia GPU before, and did not have these issues)
So maybe it's about Mesa's OpenGL implementation and I need to create an issue in their repo

I've had a little time to figure it out. I tried to run the game through Zink (Very simplistically speaking it converts OpenGL calls to Vulkan). And it solves both problems.

Mesa OpenGL
2024-03-11_17-37-49
Mesa Zink (OpenGL -> Vulkan)
2024-03-11_17-40-29

So it is suggested that the problem is actually in Mesa's implementation of OpenGL
I'll create an issue about Stalcraft OpenGL in the Mesa repository one of these days as time permits

mesa repo issue

Kkjirc 2024-04-09 github

news:
This problem is probably related to mesa shaders.
It affects not only Stalcraft, all other opengl games (minecraft etc).
At least navi32 (RX7700/7800), navi33(RX7600) are affected.

solution:
Starting the game with a variable (launch option) AMD_DEBUG=useaco %command% works for me at the moment

If that doesn't work, try AMD_DEBUG=w32ps %command%, also you can try to run game through Zink MESA_LOADER_DRIVER_OVERRIDE=zink

Since the question is not related to proton, I'm closing the issue. Mesa's issue on this problem.
