Hi,

I am running openSuse Tumbleweed KDE and lately I had the issue of every aurorae themes not working and not displaying any windows border, at the exception of Breeze and Plastik working great. The only way I can force a custom aurorae theme is to select a Look And Feel, in this case McMojave, and the theme will work as intended. However, themes are still broken (gray box) in the Windows Style menu, and sometimes when starting up the computer I have to do the manipulation again because the custom aurorae theme does not work. I of course tried updating the computer, but no luck here either. Maybe I should try to do sudo zypper dup ?10.0.0.0.1 192.168.1.254

If you run "kcmshell5 kwindecoration" (or via systemsettings5), there should be a window border size setting at the bottom.
