Created attachment 121800 [details] xorg log I have 2x2 virtual desktops in plasma 5 using opengl 3.1 (GLX) compositing. I updated to the latest driver 2.99.917-546-gde7407d20703 recently. (And I updated from kernel 4.3.x to 4.4.1 recently too.) When I switch desktops, sometimes the screen is not redrawn at final position. I still see about 100 px shifted screen, like the desktop shift haven't finished completely. But when I use mouse, the screen is redrawn correctly either partially (mostly when hovering) or fully (on clicking).
