Are you running a custom theme or style?

Similar issue here, but in Konsole Maybe the same bug?

Probably yes. Which would make it not an Okular bug.
Same in Konsole.
Downgrading qt5-base from 5.15.11+kde+r147-1 to 5.15.11+kde+r146-1 fixes this issue for konsole Seems that the only difference is https://invent.kde.org/qt/qt/qtbase/-/commit/56faf7249c3857f80f6483c5070e7408c2d53961
Likely duplicate of 477700
FWIW i still can not reproduce such an issue with a very similar setup, except i don't have hidpi, are you running some hidpi zoom that is not an integer number?

I agree that this is a duplicate of https://bugs.kde.org/show_bug.cgi?id=477700 and is not okular specific. Albert, see also https://bugs.kde.org/show_bug.cgi?id=477700#c22 - it really seems to be hidpi/fractional-scaling related.
