A new update came this past week turning dri3 back on,

Please help test this if you are able.


For *me*, it's pretty good, but I've now experienced at least 3
plasmashell
deadlocks (when left idle and screen off) similar to past results
when using
dri3.  And... oddly, chrome seems to freeze similar to plasmashell
sometimes
too.

you may try add:

# cat /etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
Identifier  "Intel Graphics"
Driver      "intel"
Option      "AccelMethod"  "uxa"
#Option      "AccelMethod"  "sna"
EndSection

reading https://bbs.archlinux.org/viewtopic.php?id=208427

?? When I read this link, it says he tried that fix ^^ and it didn't work.
What's working for me is

Section "Device"
Identifier "Intel_Graphics"
Driver "intel"
Option "DRI" "2"
EndSection

well, and for others it's

Section "Device"
Identifier "Videocard0"
Option "AccelMethod" "uxa"
Option "TearFree" "true"
Option "DRI" "3"
EndSection

and so there is no identical solution for every environment and on my machine (identical hardware) the config below works perfectly

Section "Device"
 Identifier "Videocard0"
 Option "AccelMethod" "sna"
 Option "TearFree" "true"
 Option "DRI" "3"
EndSection
