screencast showing the jittering

When starting or aborting a text selection and when resizing the Okular window, the document content jitters slightly (see attached okular-jitter.gif). It seems the problem only occurs when the UI is scaled. I use 1.25 for QT_SCREEN_SCALE_FACTORS (configured to 125% via systemsettings). When starting Okular with unset QT_SCREEN_SCALE_FACTORS, I cannot reproduce the problem.

I started to notice the problem first with the recent version of Okular (23.04.0).
