F33 Gnome font error screenshot
Description of problem: Gnome default font unreadable
Version-Release number of selected component (if applicable):
Gnome 3.38.0, normal wayland windowing
How reproducible: all the time
Steps to Reproduce:
n/a, normal install
Unreadable system font for the Gnome GUI and icons
Application fonts (e.g. terminal) appear to be ok.
Readable font, same as F32
Hardware is a ThinkPad T500 with AMD Rv635 graphics chip, 1680x1050 default resolution.
All updates applied as of Beta+1 date (2020/09/30T12:00EST)
Screenshot showing unreadable icon and other difficulties attached.
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.
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.
