--- Comment #13 from Michael B toxatec@web.de --- I did some quick testing with a slackware64 live system on a USB drive with wine-staging-2.13.
I could reproduce the issue on a machine with Nvidia graphics and nouveau drivers. With LIBGL_ALWAYS_SOFTWARE=1 it didn't happen. It used LLVMpipe I think.
Tested on another machine with AMD Kabini hardware (radeonsi), no image freeze.
When the freeze did happen I could press "Win+D" or "Ctrl+Alt+D" (Toggle Desktop) and re-enter the game to fix the freeze. The game would then run smoothly.
Can you confirm that "Toggle Desktop -> re-enter" makes the game return to normal? On a recent wine version?
