Description Christoph Feck 2022-11-30 02:26:59 UTC

SUMMARY
With compositing enabled, popup menus are not rendered initially, only when a hover event causes a redraw.
With compositing disabled, everything works correctly. It was also working correctly a few weeks ago.

STEPS TO REPRODUCE
1. right-click on the desktop without moving the mouse
2. observe that no popup menu is visible
3. move the mouse into the direction of the popup, then it appears

SOFTWARE/OS VERSIONS
kwin master a93ccbd7
Mesa-22.2.4-333.1.x86_64
X11, NVIDIA 525.60.11

ADDITIONAL INFORMATION
Animation speed is set to "Instant", and Popup desktop effects are disabled.

This should get fixed with https://codereview.qt-project.org/c/qt/qtdeclarative/+/447075. 

Even if the title sounds different.
