After starting my KDE Plasma 5 session everything is rendered find. Yet
(always) after some minutes the rendering of window decorations, task bar, and
popup menus starts to break, resulting after more and more increasing rendering
problems in an unusable desktop. When this happens, I get the following output
from dmesg:
