Bug ID: 55350
           Summary: explorer.exe:explorer - test_taskbar() often fails in
                    Wine
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2

explorer.exe:explorer - test_taskbar() often fails in Wine:

explorer.c:43: Test failed: Expected (0,0)-(0,0), got (904,0)-(1024,768).

See https://test.winehq.org/data/patterns.html#explorer.exe:explorer

This happens almost systematically on fg-deb64-* but also happens randomly on
the TestBot's debian11 VM, GitLab's gitlab-debian environment, and Remi's VMs.
This also impacts merge requests sometimes, for instance MR!3413 on 2023-07-26.

This might be caused by a change in either work area or screen size between
when explorer was started and when this test was run.

The run where I got this has some failures in ddraw:ddraw2 that suggest the
display size may not have been properly restored:

ddraw2.c:3558: Test marked todo: Got unexpected hr 0.
ddraw2.c:4090: Test failed: Got unexpected screen width 800.
ddraw2.c:4092: Test failed: Got unexpected screen height 600.
ddraw2.c:4097: Test failed: Got unexpected screen width 800.
ddraw2.c:4099: Test failed: Got unexpected screen height 600.
ddraw2.c:4103: Tests skipped: Following tests require two monitors.
ddraw2.c:4508: Test failed: Display mode restored after good
ddraw1::SetCooperativeLevel call
ddraw2.c:4521: Test failed: Display mode restored after
ddraw1::SetCooperativeLevel(SETFOCUSWINDOW) call
ddraw2.c:4537: Test failed: Display mode restored after good-bad

ddraw2.c:4556: Test failed: Display mode restored after ddraw1-ddraw2

So my guess is that this is caused by bug 55483.
