Created attachment 130849 [details] Screenshot I initially reported this bug with openSUSE and the KDE teams. It was ultimately concluded that it's a problem with Mesa or the Radeon driver. As such I was encouraged to post about it here as well. Links to the other bug reports: https://bugzilla.opensuse.org/show_bug.cgi?id=1033598 https://bugs.kde.org/show_bug.cgi?id=378663 In summary: This is a problem that affects Linux users running the KDE desktop. After a recent openSUSE Tumbleweed snapshot, I found that KWin no longer renders Aurorae themes. Other themes work fine however, and this only affects Aurorae ones... Plasma also has no issues rendering desktop elements. The problem happens both with and without desktop effects enabled. The space where the titlebar and border should be becomes completely empty, with no graphics or text or buttons showing. However the blur effect is still functional in those areas, and clicking and dragging on any window component works correctly (even if they're invisible). Today I found the culprit as well as a workaround, thanks to Martin Gräßlin in the same report on the KDE bug tracker. The issue only happens when using egl instead of glx as the backend of KWin. This can be modified by opening ~/.config/kwinrc in a text editor and changing: GLPlatformInterface=egl to GLPlatformInterface=glx Anyone with a Radeon card should be able to reproduce this, by doing the reverse of the above and switching their KDE desktop to egl. I understand the driver developers need to figure out what's breaking it, which hopefully won't be difficult using this test case.
