--- Comment #4 from Cheah Kok Cheong thrust73@gmail.com --- I have a similar problem with another app using wine 10.0 stable
It's a Vulkan demo app and can be downloaded from https://www.geeks3d.com/dl/show/50110
Steps to reproduce problem:
1. Run the demo's exe file, the demo will start in windowed mode [maximised]. 2. Unmaximise the window. 3. Minimise the demo window to show desktop [I do this by clicking the "minimise all open windows and show the desktop" icon on the XFCE panel taskbar] 4. Bring back the demo window [I do this by clicking the same icon again] 5. The demo window will turn black randomly between one to five minimise window action.
Interesting observations:
1. If the window's size is maximised [app starts maximised], it can be minimised to desktop many many times before hitting the same problem. 2. While bringing back a minimised window, the demo window shows "black" momentarily before display is shown.
I'm using Xubuntu 22.04 with XFCE 4.16.3 and Nvidia driver 550.120
