I don't recall ever seeing this, and I believe i would have noticed, so I think this is a regression
This only seems to occur for ubuntu apps (not puritine/xmir apps)
This is probably best demonstrated with the Clock app because of the trusted prompt - which in the clock app case actually holds the large window on screen

steps to repro
1) connect bt mouse
2) connect slimport to device
3) launch clock app (or any other ubuntu app and keep your eyes on the screen for the flicker)
