Please post the output of `qdbus org.kde.KWin /KWin supportInformation`. Does firefox run with native wayland support?

Comment 3 Vlad Zahorodnii 2023-02-06 13:35:15 UTC

Can you reliably reproduce it? Does it happen when using default decoration theme (breeze)?

Comment 4 gus 2023-02-06 16:09:52 UTC

I cannot reliably reproduce it. It has happened multiple times, but not every time. Only on the firefox window so far.

The them was Breeze Dark. I moved back to Breeze to see.

Comment 5 Vlad Zahorodnii 2023-02-07 08:10:24 UTC

Comment 6 gus 2023-02-07 13:47:27 UTC

I have not seen that bug since moving to Breeze theme (instead of Breeze dark).

Comment 7 Vlad Zahorodnii 2023-02-10 08:41:10 UTC

> I have not seen that bug since moving to Breeze theme (instead of Breeze dark).

There's no such decoration theme as "breeze dark". Can you clarify what you mean by "breeze dark"?

---

I tried various aurorae decorations, decorations handle moving between screens fine. I'm afraid it's an inactionable bug report.

Breeze dark theme

Comment 9 gus 2023-02-10 15:11:14 UTC

Thank you Vlad for looking into this.

The glitch happened a couple of times when I first started to use 5.26.90. But since I changed theme (back to the original dark them even), I have not seen that glitch manifest itself again. Maybe doing so fixed the setting issue somehow?

I agree with you that at this point this is not a reproducible bug.

Comment 10 Vlad Zahorodnii 2023-02-13 09:38:59 UTC

Okay, reopen if there's more info.
