Public bug reported:

When activating expo mode, either through the icon in the launcher or
using super-s, dragging of a desktop causes really ugly screen flicker.
The flicker is almost as if a snapshot of desktop 3 flashes on desktop 1
or desktop 2 flashes on desktop 4. It's like all the desktops suddenly
swap around for a split second. Very ugly and detracts from the overall
feature and experience. This issue did not exist before Unity.

I have attached a video showing this issue.
