Plasma Shell crashing with Wayland

After updating Manjaro and some parts of KDE Plasma, this includes the plasma-shell and the interface has been crashing, along with the unresponsive keyboard and sometimes the system takes a long time to shut down or restart with a black screen. Through Htop I noticed that the plasma-shell processes running Wayland simply no longer request CPU usage after about 5 minutes of pause (when the system is not being used) and only “react” when there are mouse events, for example, Using a multimedia key such as volume or play.
I reinstalled plasma-wayland-session, switched to X11 and back to Wayland, re-upgraded Wayland packages, but to no avail. Has anyone ever experienced this?

KDE Plasma 5.26.4
KDE Frameworks 5.101.0
Qt 5.15.7

See if this is the case and if the suggested “fix” will help


Thank you very much :metal:, the solution worked.

To know the Mesa version:

glxinfo | grep "OpenGL version"

To properly downgrade:

sudo  DOWNGRADE_FROM_ALA=1 downgrade mesa

Check which version is mentioned, in this case it is 22.2.4 (146 in the list).
