corrupted screenshot

SUMMARY

First of all, I use 125% scaling on my main monitor.

When I resize gwenview window, sometimes it corrupts image (as seen on screenshot). I'll also attach real image so you can see it's not corrupted.

STEPS TO REPRODUCE
1. Open image
2. Resize window

OBSERVED RESULT

Image being visually corrupted

EXPECTED RESULT

Not messing with image

Cannot reproduce. Can you check whether this stil occurs on Gwenview 25.08?
If yes, a screencast would be sweet.
