Fonts in Chrome 95.0.4638.69 (Official Build) (64-bit) in Ubuntu 20.04 KDE Plasma are often appearing white or multicolored. See four examples below.

The fourth is rainbow coloring while visiting askubuntu.com. I have refreshed the font cache using fc-cache, but that did not help. I have also tried starting google-chrome-stable with and without "--use-gl=desktop --ignore-gpu-blocklist". The improperly rendered fonts flicker whenever the page is scrolled.
I fixed the problem myself. On the Fonts page in System Settings make two adjustments:
With these changes, chrome fonts render properly.
