--- Comment #13 from Bastian Beischer <bastian.beisc...@rwth-aachen.de> ---
I'm suffering from random freezes in kwin which match the subject of this bug
report as well.
I have an Intel GPU and I'm using driver version 26f8ab5 (SHA1 from Intel
Driver git repository). My laptop is a Lenovo W520. I'm using "OpenGL 2.0" and
"GLX" in compositor settings.
I'm using Qt 5.7 and KDE Plasma 5.7.1. I was able to attach with gdb to
kwin_x11 last time the desktop froze (mouse is still moving but nothing is
"clickable"):

Killing kwin_x11 (with -9) and restarting it fixes the desktop.
