I haven't experienced this problem in a long time. So from my point of view
this issue can be closed.

This issue report is quite old. Can you please confirm, that it still persists
with KDE 5.23?

I can confirm the problem and have found a fix.  I have an AMD C-60 APU and am
running plasma 5.8 on Neon / Linux 4.4 kernel.  I am running off of the stock
Mesa radeon r-600 driver.  What I found is that the flickering would not be as
common in the first minute or so but then is more pronounced when viewing
videos or the alt-tab desktop effects it is on both the OpenGL 2.0  and  3.1
versions.  I however turned the V-Sync to never and haven't had any problems
with the flickering since.  So the Bug is related to the V-Sync code.

ATI M7740 FireGL card (I know pretty old) and I have the same issue.  All fixes
in that askubuntu link do not work for me.

Are you talking about this issue? The 3rd method in the selected answer seems
to have fixed opengl 2.0 for me as a working work around.
Using Ubuntu 16.04

btw possibly a duplication of https://bugs.kde.org/show_bug.cgi?id=340489
