           Summary: Turtle WoW client can alt-tab back to desktop once
                    only, next time display is black
           Product: Wine
           Version: 10.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

Morning, Gents.

I run the TurtleWoW World of Warcraft client, which is the original WoW client
from Blizzard, but with substantial modifications made by the TWoW devs.

I updated Wine to 10.0.

Prior to this, I could alt-tab without problems back to desktop (XFCE on
Debian) quite a few times, maybe ten or so, but in the end environmental
textures would all turn black and I would need to quit and restart the client.

As of 10.0, I can alt-tab *once* without problem.  The second time I alt-tab,
when I come back to the WoW client, its screen is simply black.

I'm afraid I do not know the previous version of Wine, but I use the winehq
repo, like so;

Types: deb
URIs: https://dl.winehq.org/wine-builds/debian
Suites: bookworm
Components: main
Architectures: amd64 i386
Signed-By: /etc/apt/keyrings/winehq-archive.key

And I upgraded maybe a week or two ago; I'm pretty up to date, so I will have
prior to 10.0 a recent version.

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
