1. Install the Gnome Tweak Tool
2. Select the Fonts tab
3. Alter the default font rendering from Standard (grayscale) to SubPixel (for LCD screens)

It looks like the as-installed font configuration is failing to determine that this is an LCD screen on this laptop, and selecting a subpixel render mechanism only suitable for ancient CRTs.

Workaround does not work.

This should be a blocker for Fedora 33 release.

Comment 3 John Mellor 2020-10-11 14:01:31 UTC
Workaround: Using the Gnome Tweaks tool, change the default fonts from Cantarell to Liberation (3 places), and change the Altialiasing setting from Standard (grayscale) to Subpixel (for LCD screens).

If this change is not made in time to Fedora 33, then it needs to be documented as one of the known workarounds.
Since this bug only affects older video cards and a functioning workaround is possible, reducing severity to medium.
