Public bug reported:
My desktop system is a Skylake i5-6600 with Asus Z170 mainboard and
Intel onboard graphics, connected to a 4K monitor via DP 1.2.
I've selected "Desktop Cube Animation" as Virtual Desktop Switching
Animation.
After upgrade to Yakkety, this desktop animation shows a large dark area
in the top right corner, while the animation is in progress. The size
is exactly (?) 1/4 of the screen, and the color of the area changes
during animation. When the animation completes, everything is back to
normal.
I cannot tell if this issue is related to Kwin, or the Intel graphics
driver or some such thing.
On Xenial, this particular bug was not present, although I did have some
glitches in Cover Switch (bottom of Windows showing at the top).
