I have found multiple threads describing this issue. Some claiming it has been fixed in the latest version of parallels and others with responses saying it has very much not been fixed and is still an issue and no further responses from Parallels after that. It has not been fixed. It is still an issue for me running the latest version, Parallels Desktop 18.1.0 (53311) on an M1 Macbook Pro running macOS Ventura Version 13.0.1 (22A400) with a Windows 11 Pro 22H2 guest. For me it seems to happen at certain spots in certain UE4 games. Right now, it is happening very consistently in a particular cutscene near the end of The Artful Escape, which means I cannot progress past that point. I have sent multiple crash reports to Parallels support on this, the most recent being #412572568. In brief this is what happens: I am playing a UE4 game. I briefly see some graphical glitching, and then Windows starts to suspend. I get an error message from Parallels that it has encountered a critical graphics error and offers to send a crash report to Parallels Tech Support Concurrently with 3, Windows immediately comes back from suspension and I see an error message from the game that it has lost the graphics device and will close. The game does not actually close, but just shows me a black screen. If I force close it through the task manager (just asking it to close does not work), and re-open it, I still get a black screen. I have to reboot the guest before I get any 3D graphics back. Is there anything like a fix to this anywhere on the horizon?
