SUMMARY
This bug was previously mentioned in bug 417636 comment 34, I'm opening this report as requested by Nate.
The headers of Kirigami apps have a flicker, in the attached videos we see the
bug affecting System Settings, but I can also reproduce with other Kirigami apps like Kinfocenter (click on the sections in the left side), System Monitor (click on the pages in the left side) and Haruna video player (open settings and click on its sections in the left side).

OBSERVED RESULT
a flicker affects the header

EXPECTED RESULT
no flicker

Confirmed. I suspect this will require a rewrite of the header visibility and switching code as it is very complicated and difficult to understand right now and every attempt to fix bugs introduces new ones.

I can't reproduce this on current master.  Could you test this again, please.
