           Summary: Wait cursor does not display
           Product: Wine
           Version: 9.0
          Hardware: x86-64
                OS: Linux

Example

Starting from Wine version 9.0, the waiting cursor no longer appears when
attempting to set it to indicate a long-running operation in MFC applications
or other programs. The issue appears to have started after the commit on June
13, 2023.

Steps to Reproduce:
1. Run the attached simple MFC application.
2. Click the button "Start Long Operation"

Expected Result:
The waiting cursor should appear for the duration of the 3-second sleep.

Actual Result:
The waiting cursor does not appear during the Sleep call. The cursor remains
the default arrow.

Example Application:
The example application has been attached. It uses the most basic
implementation of the CWaitCursor class, as described in the official Microsoft
documentation:

https://learn.microsoft.com/en-us/cpp/mfc/reference/cwaitcursor-class?view=m...

Regression Commit:
The issue seems to have started with the commits made on June 13, 2023:

https://github.com/wine-mirror/wine/commits/master/dlls?author=rbernon&s...

Notes:
This issue does not occur in Windows, where the waiting cursor appears as
expected.

Environment:
Wine version: 9.0+ (possibly Wine 8.x, but not 8.0)
Operating System: RHEL 7.9, RHEL 8.10

Have you tested Wine 10.9?

The bug still exists in version Wine 10.9.
Fixing this issue is important because users cannot tell whether the app is
still loading or has frozen.

Starting with 10f5ff7f06 the wait cursor is shown when the button is pressed,
but stays after the finish dialog is shown, until mouse is moved.

Starting with 4b968267c1 the cursor stays regular during the wait period,
and changes to wait cursor when the finish dialog is shown, until mouse is
moved.

The functionality is broken, as mentioned in the description.
Tested with Wine version 10.9.

To put it simply: before the commit that broke the functionality, set_cursor
would set the cursor directly in X11. After the changes, set_cursor sets it on
the server, which is then supposed to forward it to X11. In the reported case,
the server does not forward it to X11.

You can run the example on Windows and with Wine to observe the bug.
