Public bug reported:
Performance regression and no DRI3 acceleration in xserver-xorg-video-
radeon-lts-wily, unless one specifies Option "DRI3" "1" in xorg.conf.
Then, performance is *even worse*, in comparison to
xserver-xorg-video-radeon-lts-vivid:
Desktop is laggy, video playback is choppy, tearing occurs.
Package is official Ubuntu 14.04.
I've been sticking to the -lts-vivid stack for stability, but when
upgrading to the -lts-wily stack for kernel 4.2, while the system runs a
bit smoother, video performance is severely affected.
System is a dual-core x86 Pentium laptop, 2Gb RAM.
This report was previously dismissed ad invalid.
I'm reporting it again, as it is not.
Please test both scenarios, without and with xorg.conf enabling DRI3; running
glmark2 showed correlation with performance degradation.
