Bug ID: 56008
           Summary: Running multiple apps simultaneously causes crashes.
           Product: Wine
           Version: 9.0-rc1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

My environment is as follows:
Hardware: Thinkpad E490
Operating System: Ubuntu 22.04.1 LTS
WINE Version: wine-9.0-rc1
Custom DLLs: msls31, msvcp140, riched20 (sourced from Windows 11)
Phenomenon: When I use the software "WeChat" and "CloudMusic" consecutively,
opening one and minimizing it to run in the background, then opening the other
software directly causes the first one to crash. The error codes from the
console are:

0970:fixme:winsock:setsockopt Ignoring SO_RANDOMIZE_PORT
0730:fixme:thread:NtSetInformationThread ThreadPowerThrottling stub!
0730:fixme:file:ReplaceFileW Ignoring flags 2
0730:fixme:thread:NtSetInformationThread ThreadPowerThrottling stub!
X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  10 (X_UnmapWindow)
  Resource id in failed request:  0x4800003
  Serial number of failed request:  456
  Current serial number in output stream:  456

Can you reproduce this with any other combination of applications, or just
these two specifically? Is just running the applications and switching enough
to reproduce or do you need to do some specific actions?

1. The issue is not consistently reproducible. After the program has been
running for some time, or upon locking the screen and waking it up again, a
Wine pop-up window displaying "Expression: 'nb_displayed'" will appear, and the
small icon in the upper right corner will disappear (although the program
continues to run normally in the background). If the program continues to run
in the background for a while, the described issue arises. At this point, it is
necessary to run "wineserver -k" in the console in order to be able to run
multiple programs simultaneously again.

2. Generally, before and after this issue occurs, I am usually working with
IntelliJ IDEA, and the program is running in the background.

3. I have not yet been able to reproduce the above situation using other
programs, which may be due to insufficient testing time. I will continue to try
and see.
