While running Plasma 5 on 4.4.0 the following occurs periodically:
- chromium locks up
- plasma desktop locks up
- unable to enter password on plasma lock screen

A trigger for locking chromium up seems to be to resize the window by dragging
to screen edges (top to fullscreen, left to tack up left half of screen, etc).
Otherwise, it also seems to somewhat randomly freeze over time.

Reverting to 4.3.x resolves the issues.
