Description Mariusz Libera 2023-01-28 18:28:10 UTC 
When I right click on the desktop or inside some apps like Chrome, the context menus don't show until I move the mouse cursor over them or show but with a noticable delay. Can't reproduce in all apps - Firefox and Dolphin always show them but with a slight delay. With composing disabled problem goes away - context menus show up immediately.

We cannot reproduce, 
Please ensure you've disabled any kwin scripts or effects that could be affecting this and confirm if there's still an issue.
Comment 2 Mariusz Libera 2023-02-01 17:00:52 UTC 
I was able to reproduce it on a fresh profile after disabling fading popup effect. I don't have any scripts of custom effects.

scene: Sync Window::readyForPainting() to window item visibility

If a window is made ready for painting with some delay, the item won't
schedule an update. To fix that, sync the item visibility state with
Window::readyForPainting(). When the item visibility changes, a repaint
will be scheduled.
