wrongly visually positioned window when fullscreen button was tapped

When i use the button to set my brave or chrome browser in fullscreen, it's physically correct but displayed translated a couple of pixels on the bottom (physically the window header is in the blank space on top of the screen). it sometimes happens when i drag the window on top of my screen to set it fullscreen, i could not find a 100% working manipulation, but happens most of the time using button.

My environment:
OS: NixOS 25.11pre803506.2795c506fe8f (Xantusia) x86_64

DE: Plasma 6.3.5 (Wayland)

When i tested fedora before, the bug was happening too, seems not being specific to my os, i don't know if hardware matters, i can't test any other hardware.

Please take a screenshot of the window (not the screen); is the image also translated in that?
Comment 4 RICHER William 2025-10-14 17:05:02 UTC
i updated my system and cannot reproduce the bug. my picture attachement was a screenshot, my monitor is curved, a photo would be ugly
Comment 5 RICHER William 2025-10-14 17:07:53 UTC
another glich appeared: when i pull a fullscreen chrome window, i get a wrongly rendered window. maybe an error from the same scope. i added an attachement for that

I specifically need a screenshot of the window, not of the screen. The latter can (in 6.4, not anymore in 6.5) contain the glitches that KWin caused, but the former is always a newly rendered image of only the window.
If the glitch is also in the window "screen"shot, then it's a bug in Chromium. If it's not in there, then it's our bug.
