Exclusive Mode - DX11 - Crash on Application.Quit

Unity Engine
1

Hi Unity Community,

Setting the fullscreen mode to Exclusive Mode for DX11 will cause the build to crash when Application.Quit is used.

I’m using the latest unity (5.5) from the download page.
I’ve tested it in multiple projects and on 2 different machines.

I have attached an empty project with just a UI button that calls Application.Quit, whenever i run this in DX11 it will cause the game to crash.

I have also attached a rar with the error log created.

Is anyone else experiencing the same problem or am i at fault here?

Thanks,
Thomas

Hi Thomas,

I am experiencing the same problem. A quick workaround is to use:

if (!Application.isEditor) {
     System.Diagnostics.Process.GetCurrentProcess().Kill();
}

But a fix for this problem would be nice from Unity :slight_smile:

Good luck,
Sam

I ran into this issue as well with Unity 5.5.0f3. As stated above, the problem is specific to quitting the application while in DX11 fullscreen exclusive mode. I was using the native resolution, 1080p. Killing the process seems to be a viable workaround. Thanks to Sam for mentioning that. Here’s some DXDiag info in case it helps:
