We’re seeing this in Mac builds on 2022.3.21f1 also. Seems to be only when the build is in Exclusive Fullscreen mode, with Run In Background enabled.

This happens in my production builds when players alt-tab, but only sometimes.

Using Unity 2022.3.17 and DOTS.

Stack trace from the crash dmp:

UnityPlayer.dll!GfxDeviceD3D11::presentFrame(void) 
UnityPlayer.dll!GfxDeviceWorker::RunCommand(class ThreadedStreamBuffer &) 
UnityPlayer.dll!GfxDeviceWorker::RunExt(class ThreadedStreamBuffer &) 
UnityPlayer.dll!GfxDeviceWorker::RunGfxDeviceWorker(void *) 
UnityPlayer.dll!Thread::RunThreadWrapper(void *)```

I actually found out what the problem was in our game. When using VSync on macs it seems important never to set it to anything other than Every VBlank (1). Setting it to Every Other VBlank (2) caused our game to crash every time you’d ALT-TAB and go back.

I have some indications that the same problem can occur on PC as well. But it does not seem to be as frequent as it has shown to be on Mac.
