Graphic issue after last update 2021-02-28

I’m not sure (don’t remember) if anything seemed blurry, but after I updated my system last night open windows (konsole, dolphin, firefoc, etc.) seemed to vibrate; moving up and down rapidly. I’d read of a similar issue a few weeks ago while test driving EndeavorOS: Since 5.21 there are glitches or something like that on my screen I tried the first option in the post marked as the solution (post #7 Solution), rebooted, and it worked.
