Thank you for the bug report! Please note that Plasma 5.25.5 is not supported for much longer by KDE; supported versions are 5.24, and 5.26 or newer. If at all possible please upgrade to a supported version and verify that the bug is still happening there. If you're unsure how to do this, contact your distributor about it.
Ehm I'm obviously running master. :D
https://invent.kde.org/plasma/kwin/-/merge_requests/3268 should fix it
