Created attachment 180621 [details] The default KDE Application Launcher looking completely broken (wrong outline widths, overlapping elements, broken paddings) as it is affected by the bug SUMMARY Various paddings, and even 9-slicing appear completely broken after switching back and forth from some themes, Breeze is affected too. STEPS TO REPRODUCE 1. Change Plasma Style to a non-default theme (Utterly Round from Get New... makes it very noticeable), 2. Observe how various widgets have been slightly affected by the bug, 3. Log out 4. Log back in and it'll look as intended 5. Switch back to the Breeze Plasma Style 6. Things look even more broken since the padding differences are much more stark OBSERVED RESULT The entire plasma style breaks with wrong paddings or broken 9-slicing of the svgs EXPECTED RESULT The plasma style updates the elements correctly SOFTWARE/OS VERSIONS (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: Fedora Linux 42 Kinoite KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.13.0 Qt Version: 6.9.0 ADDITIONAL INFORMATION
Can reproduce the issue.
This is much improved with today's git master (perhaps due to https://invent.kde.org/frameworks/ksvg/-/merge_requests/68) but not fully fixed yet. I still see some things looking being wrong when switching to a theme with different metrics like Utterly Round or Qogir Dark. Scrollbars and list items are noticeably affected. To reproduce it, you may need to clear the ~/.cache/*.kcache files, or even the whole cache folder.
