Oh hum, this happened today when starting QPC5v00 on Linux under Wine:

The solution is to add this bit to the command line:

Code: Select all

MESA_GL_VERSION_OVERRIDE=4.6

On my command line, I now have this:

Code: Select all

env WINEPREFIX="/home/norman/.wine" MESA_GL_VERSION_OVERRIDE=4.6 wine C:\\Program\ Files\ \(x86\)\\QPC5v00\\QPC2.exe

And QPC now works fine again. I have not updated OpenGL or Wine -- at least that I'm aware of, but I did have a new kernel update since I last used QPC. Hopefully, this will help anyone else (Derek?) suffering the same problem.

In case it makes a difference, I'm on:

64 bit Linux Mint 20.1 Ulyssa
Linux hubble 5.4.0-80-generic #90-Ubuntu SMP Fri Jul 9 22:49:44 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Wine is version "wine-5.0 (Ubuntu 5.0-3ubuntu1)"

Code: Select all

glxinfo -B

gives this:

Code: Select all

name of display: :0
display: :0  screen: 0
direct rendering: Yes
Extended renderer info (GLX_MESA_query_renderer):
    Vendor: nouveau (0x10de)
    Device: NV96 (0x648)
    Version: 21.0.3
    Accelerated: yes
    Video memory: 501MB
    Unified memory: no
    Preferred profile: core (0x1)
    Max core profile version: 3.3
    Max compat profile version: 3.3

OpenGL vendor string: nouveau
OpenGL renderer string: NV96
OpenGL core profile version string: 3.3 (Core Profile) Mesa 21.0.3
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

OpenGL version string: 3.3 (Compatibility Profile) Mesa 21.0.3
OpenGL shading language version string: 3.30
OpenGL context flags: (none)
OpenGL profile mask: compatibility profile

OpenGL ES profile version string: OpenGL ES 3.0 Mesa 21.0.3
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00

And the fix came from here: https://www.reddit.com/r/linux_gaming/c ... fig_after/

HI,

I use Mint 19.3, the stock Wine version is v3.60.

But I added the PPA foe WineHQ and installed Wine v6.01

I do not appear to have the problem you describe., but I will monitor the situation

Cheers Derek. I didn't have the problem either last week. Today, I did. I'll probably give Wine 6.xx a try when I can fit things in around the new puppy.

Cheers,
Norm
