Description
Describe the bug
Before tooltips and menus are displayed on Linux, there is a very jarring black flash. This is especially noticeable when switching between menus.
To Reproduce
Steps to reproduce the behavior:
- Open a toolbar menu, context menu, or trigger a tooltip.
- Observe the black flash shown before the menu appears.
Expected behavior
That the menu should immediately appear without a flash.
Screenshots
Static frames from the video



Desktop:
Linux 5.10.0-9-amd64 #1 SMP Debian 5.10.70-1 (2021-09-30) x86_64 GNU/Linux.- Reproduced in the latest nightly build.
Additional context
The application header (the "MuseScore4Development" in the top bar) is flickering in and out, seemingly at random; could this be related?
