           Product: Wine

                OS: Linux

Created attachment 76917
  --> https://bugs.winehq.org/attachment.cgi?id=76917
example: notepad

In wine 9.15 on wayland (using kwin_wayland with the proprietary NVIDIA
driver), window subsurfaces are rendered blank.

When opening there are al lot of errors shown:

016c:err:waylanddrv:wayland_window_surface_flush missing wayland surface=(nil)
or buffer_queue=(nil), returning

On a hunch I reverted
https://gitlab.winehq.org/wine/wine/-/commit/b9879d5adc1cd98a6ceb7d087c4533f...
since that seemed as it might have caused it, and thad fixes the issue.
