KDE Plasma 5 Problem Traced To Bug In Intel Graphics Driver 56
prisoninmate writes with news that certain complaints about the KDE Plasma 5 desktop environment may not be KDE's fault at all:
Apparently, KDE Plasma 5 runs just fine, and the issue is related to a serious Intel Graphics Driver Stack bug. The good news is that a workaround for the bug is already available, and it requires you to modify the /etc/X11/xorg.conf.d/20-intel.conf file from your Linux kernel-based operating system, by switching back to the older UXA acceleration method instead of the default SNA method used in many distros.
