[SOLVED] AMD GPUs May Suffer from Display Artifacts After LLVM 15 Update

This issue, caused by incompatibilities between Mesa and Link-Time Optimisation (LTO), has been resolved with mesa v1:22.3.1-2.

Ref: https://gitlab.freedesktop.org/mesa/mesa/-/issues/6911

One of our AOSC OS maintainers has recently discovered that, after the LLVM 15.0.7 update, characters went missing in certain SDDM and KDE applications. We are currently investigating this issue. If you use an AMD GPU, please do not update your system until further notice.

If you have already updated your system and are affected by this issue, please downgrade your system using the following command:

sudo apt install mesa=1:22.3.1

This should at least make your system usable. We apologise for any inconvenience this may have caused.
