Are you running a custom theme or style?

I only changed the icons. After I change it back to default, this problem still occurs.

Similar issue here, but in Konsole

Maybe the same bug?

konsole
Comment 11 Albert Astals Cid 2024-01-01 12:09:17 UTC
Probably yes.

Which would make it not an Okular bug.
Comment 12 blackst0ne 2024-01-26 00:53:29 UTC
Same in Konsole.
Comment 13 Henry Zhang 2024-01-27 01:56:31 UTC
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
Comment 15 Albert Astals Cid 2024-01-30 22:59:22 UTC
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?

Yes.

I could reproduce on 150% scaling but not 100%.

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.
