Long story short, I tried to downgrade mesa, it worked, except one stubborn i686 package (probably from wine or lutris for 32 bit games), so I made something stupid and removed it, and then my whole Plasma died, black screen after reboot. But it is fine, I restored the system from timeshift again 
So my test was inconclusive, because after downgrading all of them, except that one, I was seeing that all packages were 24.0.5, but vulcaninfo was still showing 24.1.2 so I guess downgrade was not successful.
