Anyone upgraded to 26 and seen Nouveau performance just absolutely TANK?

So my desktop was running GREAT with 25. But of course, new and shiny...so I upgraded to 26.
Nouveau performance suddenly was awful. Konsole was unusable because all the text was so mangled, switching activities was super slow, moving windows would show "shadows"
across the screen. Switched to the proprietary driver and all the issues went away.
Just wanted to check if anyone else saw this same thing, or if my install just suddenly stopped liking nouveau for some reason. I'm not really looking to try to fix it,
the proprietary is working, so although I do prefer the open source drivers when I can,
as long as it works I'm happy enough.

I did want to get the blob, but was put off it in #fedora on IRC.

After using it at work today, I'll post back my experience.

No problems with video after using it ~10 hours yesterday. In addition to the laptop screen,
there are 2 external monitors connected using DP cables through a DP MST hub to a dock. My
DE is Gnome.

Never saw a slowdown with Nouveau moving from F20 through to F26+ on my recently replaced HP desktop with onboard GeForce 6100 graphics. Mate DE, Marco WM with software compositing turned on.

I do have some issues with the 3 screens (laptop plus 2 external using DP to DP MST hub to Lenovo docking station).
Occasionally when the laptop is placed back on the dock, with the monitors already on and connected to the dock,
then the laptop is turned on, there is flickering on the external screens, and the screen to the left of the laptop
will have it's image somehow superimposed on the screen to the right of the laptop. A reboot has stopped this issue
every time so far.

This weekend I will have time and plan to test the Nvidia blob.
