Since updating to Fedora 26, I get a strange screen tearing effect on any moving image (scrolling webpages, watching live video, anything that moves). The effect is unnoticeable on static displayes. The effect is like this diagram:
http://imgbox.com/TqED2C76 There's a portion at the top of the screen related to one moment in time, with a dividing line going across the screen, related to another moment. The really strange thing is that there's a diagonal portion to this division. The division slowly rolls down the screen, so it can be seen that the screen refresh rate is different from the source material (whatever it may be). According to driconf, which offers options I know nothing about, and offers nothing I see related to setting any vertical sync options, the graphics set is using: NV98 (nouveau) The display configurator (I'm using Mate) gives me 60 or 75 Hz refresh rates, and they will change the rate that the dividing line rolls down the screen, but not eliminate it. I'm using a LCD screen connected through a DVI cable (both ends, no conversions). Mate's display configurator says its DVI-I How can I get rid of this? -- [tim@localhost ~]$ uname -rsvp Linux 4.13.5-200.fc26.x86_64 #1 SMP Thu Oct 5 16:53:13 UTC 2017 x86_64 Boilerplate: All mail to my mailbox is automatically deleted.
