--- Comment #29 from Diego Viola diego.viola@gmail.com --- OK, I was able to install Mesa system wide, glxinfo tells me this:
Mesa 19.0.0-devel (git-8daf5bb209)
Which is the commit prior to the bad commit I mentioned above.
Sadly xterm is still breaking as usual, the output disappears as I Shift+Page Up and nothing changed in that regard. :(
