[Bug 1384512] Re: Plasma 5 frequent screen freezes

[Torsten Römer]

Pressing ALT+TAB allows me to cycle through the windows but does not
unfreeze the desktop once it is frozen on a Lenovo L420 with Intel i5
and Intel HD 3000 graphics with a dual-screen setup.

Switching from OpenGL 2.0 to 3.1 did not help with the freezes, but
switching to XRender did. Also some animations like fading in/out
popups/tooltips is now much smoother. And a lot of other things seem to
work properly now, like dialogs correctly being placed on top,
applications opening in the primary display and so on.

Also, I had the issue with the giant .xsession-errors file before, which
is gone now.
