Updating mesa to 22.214.171.124 breaks Superslicer 2.3.55. I restored my system to the situation before the update with Timeshift which includes the previous mesa version 20.3.4-3. All seems to work like it is supposed to. Added mesa, mesa-vdpau as IgnorePkg in /etc/pamac.conf before updating to this release.
