yeah, from Xorg.log:
X.Org X Server 1.18.99.902 (1.19.0 RC 2)
Release Date: 2016-10-28
that is why nvidia is broken .
That new version of X also gives problems to the radeon driver. When I
try to do anything that requires significant graphics processing
(pygame, vlc, mplayer, ffplay), they run about 1/8 speed (ffplay
doesn't but eventually hangs). It isn't noticeable in the GUI because
I'm so slow, as a human (last time I checked). I still have X 1.19 in
rawhide, and it is slow. When I downgraded X to 1.18 in F25, everything
started working properly again.
They must have turned off optimization, or hardware acceleration, in
these test candidates, or something. So, as a workaround, find out
which xorg-x11-server* packages you have installed, go to koji and get
them for X 1.18 and do a local dnf -C downgrade of X. Then use -x
xorg* on any future updates to stay at 1.18.
