GNOME Shell text & icons garbled and glitched suddenly (glyph and icon corruption)
Affected version
Fedora 34 but also Arch Linux, GNOME Shell 40.2, always happens in Wayland, may occur in Xorg (Does not occur in Xorg.).
Bug summary
At random times through the day, I'm forced to log out to fix garbled unreadable text in the Shell.
Steps to reproduce
I don't have a reliable step-by-step of this, it just happens at random. One thing in common is using the Shell for a long time (some hours).
What happened
All text and icons got glitched and got unreadable, looks blocky and glitched.
What did you expect to happen
It shouldn't suddenly get garbled and glitched.
Relevant logs, screenshots, screencasts etc.
Last comment has the screenshot.
