Bug ID: 58804
           Summary: Incorrect ConfigureNotify processing in xfce
           Product: Wine
           Version: 10.16
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winex11.drv

      Distribution: ---

When switching from windowed mode to maximized mode in Notepad and back, a
situation arises in which the window retains its size as in maximized mode.

Example:
1) Launching wine notepad  
2) A window opens with dimensions of 800x600
3) I switch to maximized mode and the window changes size to 1024x800
4) I switch to windowed mode, the window becomes 800x600 in size for a split
second, and eventually retains the size of 1024x800 (while the mode becomes
windowed)

The bug is reproduced in xfce, I did not observe this bug in mate.

After investigating the problem a bit, I noticed that this behavior is due to
incorrect processing of repeated ConfigureNotify requests with the value
send_event=True in X11DRV_ConfigureNotify.

This is a regression. The bug appears for the first time after the commit
https://gitlab.winehq.org/wine/wine/-/commit/0f1d999bb878ea54214057d3662c116...
, which added asynchronous event handling. Returning to the synchronous method
solves the bug
