Actually the trigger is not in Breeze, but a change in kconfigwidgets 5.98.0. It just happened that doing test upgrades of Breeze also pulled in the 5.98.0 kconfigwidgets packages.
The commit that seems to be the issue is: https://invent.kde.org/frameworks/kconfigwidgets/-/commit/8c078b50fc867df0396c7cf76ff000a747de1043 It does seem to be a reasonable change from KDE, so unclear whether this should be a KDE bug, or if it should really be a lxqt issue where lxqt mishandles such changes. KDE does not have an issue with the change, only lxqt does. ** Also affects: kconfigwidgets (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to breeze in Ubuntu. https://bugs.launchpad.net/bugs/1992196 Title: Various highly noticable graphical glitches have all started happening in Kinetic at the same time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/breeze/+bug/1992196/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
