Hello Ian,
I am observing a similar behavior since a while. Could you try restarting the kwin session. (Or rather: Start a new one with "kwin_x11 --replace"). If the problem vanishes, I would be quite sure that it is the same problem.
logging out cures the problem for me.
The effect on my PC is about the same one like in this video (not made by me):

Till now I wasn't able to narrow it further down. Sometimes I had the impression that VLC is able to cause the problem. But it is not the only application.
It may be interesting that I noted the same behavior on an Arch Linux installation on the same PC. To be exact: I reinstalled the PC because I hoped that plasma on OpenSUSE would be slightly more stable.
Eventually this problem depends on the used graphics hardware?
I have a Radeon card. hwinfo --gfxcard gives the following model: Model: "ATI Turks XT [Radeon HD 6670/7670]"
I'm using the open source radeon driver.
Kind regards
Christian

Try using the Vivaldi (64bit) browser for a while, use the mouse wheel to scroll up and down in various sites. i'm only playing with it for reading newspaper sites like the guardian, telegraph, huffington, metro and some of those sites hate being scrolled via the mouse wheel (though no problem in other browsers) If the pages start to flicker when scrolling then exit the browser and watch the desktop do the same for a while. Admittedly, vivaldi is a work in progress but i have no idea what to report as i can't get it to do this every time. Just wish i could record it to show it happening.
i'm concerned that it affects the desktop after the browser has closed. I'm using kwin/plasma 5 - latest tumbleweed versions
regards
Ian
