Hi, yes, newest mesa with git-head solves the white screen, I can get into main menu properly.

Is this perhaps similar to the issue in Sleeping Dogs (#872)?

Mesa upgrade does cause some other problems though:

• gdm3 (as usual) does not start properly after change in mesa
• under KDE steam takes a lot of CPU-time constantly (>80%)
• basically every screen operation under KDE becomes horrendously slow upto point where I need to forcibly reboot the computer

It might be that something went wrong while building it but that is a separate issue then.

Most likely the bleeding edge of software development living up to its name. Blind guess that https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/14120 is what you're looking for, but that is getting off topic.

If I understand the issue report connected to the workaround correctly, this is an issue with the game's OpenGL shaders. Since Sleeping Dogs (DE) is a DirectX 10/11 game, it is summary unrelated to the issue seen with this game.

It looks like Mesa is expecting the application to tell when it needs to apply a compatibility mode. Is there a way Proton could inform Mesa about these when needed? I don't see any related code changes on Mesa-side for this, just what looks like a configuration change?

Since Sleeping Dogs (DE) is a DirectX 10/11 game, it is summary unrelated to the issue seen with this game.

The issue seems to be in shader-related code and I guess GLSL/HLSL shaders are built to SPIR-V/NIR in Mesa so they might share same codepaths eventually regardless of API used by application?

With Mesa 22.0-rc1 game works fine.
