Comment 3 FishBoneEK 2025-10-19 13:31:35 UTC

Recursion prob?

Comment 4 FishBoneEK 2025-10-19 13:33:57 UTC

Also the issue is pretty easy to reproduce on my machine, even with other widgets. Wonder if it's the same on other machines?

Comment 5 David Redondo 2025-10-20 08:03:34 UTC

I think this was fixed by https://invent.kde.org/plasma/libplasma/-/commit/040e457a6c0706ccf0db40862456ca19791a603e  but was never backported to 6.4
