Public bug reported:

Before updating to Ubuntu 24.04, I do sudo apt upgrade to update my
packages on Ubuntu 23.10 first.

Then I found that every program in GTK4/Libadwaita renders with missing
characters, even gdm (I cannot take a screenshot of gdm, but the
problems are the same).

I toggled "Antialising" in GNOME tweaks, and some characters return
TEMPORARILY. Then I opened a new GTK4/Libadwaita program, problems re-
occur.

AND I FOUND THAT the "Graphics" Section (the driver name) has been
changed to "AMD Readon 680M" after the update (I think it is something
like "AMD Rembrandt" before sudo apt upgrade). (I toggled in GNOME
tweaks to make the window display graphics info; if I re-open it, fonts
will be missing again)

If I hover on the place where text should display, some texts may
display but icons would not.

This problem affects my life qualify, thus I need to make clear where it
is the problem. GTK4? Libadwaita? Graphics? Ubuntu? Because problems
does not occur on GTK3 based apps, thus I can submit this issue in
Firefox.

I tried to open GNOME Calendar and use journalctl to capture logs
