Public bug reported:
sometimes (very rarely) windows of different apps start blinking with
interval of 0.5 sec or so; it stops after switching focus to another
window;
the bug is present at least for 9 months (since April 2017th); and it
was detected on 2 different configurations of laptops
I suppose, it may relate to some 3rd party's desktop app I use;
but different apps are blinking, and my configuration of used software is
rather standard for web developer
