           Summary: Empire Earth Gold doesn't start in virtual desktop

      Distribution: ArchLinux

When I start the game in virtual desktop mode, all I get is an empty and
unresponsive virtual desktop screen. The game executable is lingering in the
process list with 0% CPU usage. I have to kill the Empire Earth.exe process
manually.

The game starts properly in Wine's full screen mode.

Bisecting revealed that the problem occurred since
commit 4573910acc2783a3f678a428aa313377b09a04e8
win32u: Move D3DKMT vulkan implementation out of winex11.

The demo version can be used to reproduce the problem.

I'm using X.Org X Server 1.21.1.13 with Nvidia binary drivers 550.40.63.

Still present in Wine-9.10.
