Comment 1 fanzhuyifan 2024-02-25 03:20:27 UTC

Can't reproduce on wayland. Is this on X11? Could you upload a screenshot?

I can reproduce.  I had to click back and forth the Float setting a few times before it happened though.

Comment 4 duha.bugs 2024-02-25 10:12:59 UTC

Can also reproduce on Arch + Git Master BUT ONLY when the floating option is disabled when you enter the panel configuration.

If floating is enabled when I enter the panel configuration I can not reproduce.

Comment 5 Nate Graham 2024-02-29 17:38:04 UTC

Can also reproduce the issue after toggling the floating setting on and off a few times. But only for a horizontal panel; I can't reproduce it ar all on a vertical panel.
