Hi, I’m using GPU-PV in Hyper-V with Ubuntu 22.04. The GPU-PV is the new Microsoft GPU virtulization technology. When login with the GPU-PV disabled, GNOME behaves normally except no animations. But if login with it enabled, the GNOME will show the desktop a while and then enter black screen, only the cursor visible. I tried to open any window and it did function but nothing can be displayed, just black screen. If I open firefox, the firefox window shows normally(I can even run WebGL with hardware acceleration). It’s very strange.
