I’m unfortunately getting frequent Access Violation Errors when running Heroes of the Storm through Proton/Wine on Linux.
I’ve tried multiple Version of Proton, Different Settings, etc. but without a definite fix.
Turning off DX11->Vulcan translation (DXVK) seems to (maybe) prevent the error, but the game becomes unplayably stuttery (expected without the translation).
It would be super if I could maybe get some technical Pointers to what might be causing this? With more details I could also try to open a Proton Bug report, but so far I have not enough details 
EDIT: SOLVED 
I figured out how to fix it 
The problem is probably caused by the compositor, i switched to launching the game with gamescope and had no crashes since
For reference if somebody has similar issues under Linux:
In Lutris:
- click configure
- enable the “Advanced slider”
- go to System options
- enable “enable gamescope”
- setup a proper output resolution
- window mode: fullscreen
- custom settings: --force-grab-cursor (this is not relevant to the fix, but without this the mouse cursor won’t be captured on multi monitor systems
Hope I can help fellow Linux Gamers out
Crash Info:
The game most of the time crashes after ~10-15mins (occasionally sooner) in QM or Ranked/Unranked, Aram rarly crashes. After rejoining I can play normaly, and I have not yet experienced 2 crashes in a single game.
I can watch the replays without issues, so it probably is not triggered by a specific in game event.
The crashes seem to be centered around a common address space
- DBG-ADDR 0000000141AA221F
- DBG-ADDR 0000000141C168E0
- DBG-ADDR 0000000141AA9F9F
