Hello @Mart-Bogdan, this sounds like the expected result for mesa/i965. It advertises OpenGL 3.0 for compat contexts (and supports OpenGL 3.3 core contexts) and you've found a reasonable workaround if it works.
With newer hardware, mesa/iris exposes support for higher compat contexts, but iris support has not been extended backwards to support Sandybridge. My understanding is that the Intel devs have pondered what it would take to add support, and wiring up support for older than Broadwell chips would slow down the newer driver for all users, which is why it hasn't been prioritized.
I confirm that on AMD RX590 game runs on Linux like a charm and It could be moved to the lsit of supported by Proton titles!
No mouse flickers, stable 58-60 FPS.
System Info: https://gist.github.com/Mart-Bogdan/b03853384b8df14c56ff113adc9ec01e
GPU: Radeon RX 590
Driver/LLVM version: 4.6 (Compatibility Profile) Mesa 20.0.7 (POLARIS10, DRM 3.36.0, 5.6.15-1-MANJARO, LLVM 10.0.0)
Kernel Version: 5.6.15-1-MANJARO
Proton version: 5.0-9
P.S. setting compatibility env variable tweak didn't affect the game and it runs normally without cursor flickering. I still suggest enabling this env variable by default. (But I'm not an expert and have no clue what is it doing, perhaps I am wrong)
This game is not able to launch on Proton 9.0-2+. Proton 8.0-5 is working.
I think the culprit is the following line in the log:
10340.690:0124:0128:err:seh:NtRaiseException Unhandled exception code c0000005 flags 0 addr 0x53b520
It does not exist in the logs which are generated with version 8.0-5.
Proton 9.0 Experimental: steam-365360.log
Proton 8.0-5: steam-365360.log
Hello @WasmachenDennSachenSo, please copy your system information from Steam (Steam -> Help -> System Information) and the contents of Steam Runtime Diagnostics from Steam (Steam -> Help -> Steam Runtime Diagnostics) and put them in a gist, then include a link to the gist in this issue report.
It might be interesting to test how the game behaves with the launch options set to PROTON_DISABLE_NVAPI=1 %command%.
Here you go,
The game is starting in Proton 9.0-2+ with the variable PROTON_DISABLE_NVAPI=1 set!

Thank you for this blazingly fast fix! :)

System Information
I confirm:
Protonlogs:
Default settings:
steam-365360-no-opengl-hack.log
With applied OpenGL hack:
steam-365360-opengl-hack.log
Symptoms
With default proton settings game launches and shows a black screen, only cursor could be seen.
Reproduction
Launch game from steam with default options.
Hotfix
I've noticed on Lutris page recommended setting: add environment variable
MESA_GL_VERSION_OVERRIDE: 3.3COMPATI've tried editing wineprefix user.reg to add env variable but didn't helped (perhaps it only visible from within windows, not from OpenGL driver)
Then I've launched steam as
MESA_GL_VERSION_OVERRIDE=3.3COMPAT steamit helped.later I've altered game launch settings as:
MESA_GL_VERSION_OVERRIDE=3.3COMPAT %command%Readiness
With this fix ONLY issue with game is flickering cursor, but in other aspects game is playable, sound and other stuff works.
Suggestion
Add this environment variable as default setting.
P.S. would test on RX 590 this week, perhaps issue is actually with my Intel videocard.
