https://bugs.winehq.org/show_bug.cgi?id=57798 --- Comment #4 from Cheah Kok Cheong <thrust73(a)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 Link to article about the demo: https://www.geeks3d.com/20210219/vulkan-ray-tracing-tested-on-geforce-rtx-20... -- Do not reply to this email, post in Bugzilla using the above URL to reply.
