--- Comment #22 from Thomas Lübking <thomas.luebk...@gmail.com> ---
Ie. it's the clients GL contexts (toolbar and every plasmoid are GL contexts
via QtQuick)
Maybe the GL context of kwin is affected as well (but it would affect the
entire screen then, crossing several windows, also such not using OpenGL, eg.
xterm), but even then it's a bug in the driver (since all GL clients seem
affected)
You can disable hardware acceleration for firefox in "about:config". If KWin
becomes too annoying, resort to XRender compositing.
Marking upstream since though client bugs would be invalid, it's pretty save to
assume that KWin's GL contexts are to be affected as well.
Workaround suggestions (wild shots):
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
EndSection
