amdgpu causes GTK4/Libadwaita, etc. rendering text with missing characters

[Hinomori Shizuku]

UPDATE: It seems to be related with `amdgpu` driver, which is the default driver in Ubuntu. After disabling `amdgpu`, problem vanishes. However, software rendering is not a perfect solution.

IT SEEMS THAT `amdgpu` in later updates of Ubuntu 23.10 & 24.04 are BUGGY. As no driver alternatives are available right now for Ubuntu 24.04, now I am having a hard time.

[UPDATE] Updating to Ubuntu 24.04 DO NOT SOLVE THIS PROBLEM
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.

Besides, problems exist in Xorg/Wayland, as Ubuntu 23.10 uses Xwayland.

Problems exist in Plasma. Texts in desktop icons are missing, too.

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

If I opened gnome-calendar in terminal, terminal has no new errors messages appending.

Disabling amdgpu makes the problem to vanish, however software rendering is not an acceptable option for a Ubuntu Desktop user.

Thanks in advance.
