I suddenly started to experience this bug when I updated my NVIDIA drivers from NVIDIA-Linux-x86_64-331.79 to >= 340. The only workaround I've found is:
CCSM -> Utility -> Workarounds -> Force complete redraw on initial damage -> check (not sure if this helps)
CCSM -> Utility -> Workarounds -> Force full screen redraws (buffer swap) on repaint -> check
