Actually, behind the scenes SketchUp (on Windows) has been extensively changed to use the Qt GUI framework in Sketchup 2023 instead of the old Microsoft MFC (before SU 2023).
And yes there are still outstanding UI bugs (glitches) from this migration, which is not obvious to them (e.g. you) , who is started to use Sketchup with the “new” interface engine.
Hopefully these errors will be corrected in the near future… at least the developers are reportedly working on it…
So this kind of errors, you reported here 
, will help the devs to hunt it down… and repair.
