[PATCH 0/1] MR4916: winex11: Sync with gdi_display before closing the threads display.

[Rémi Bernon (＠rbernon)]

This is a synchronization point that was missed in a6bc5f34b87393e04ff46659f518f2e7094cc7e4, as XCloseDisplay implies the destruction any every remaining top-level window.

[PATCH 1/1] winex11: Sync with gdi_display before closing the threads display.
