Created attachment 134723 [details] dmesg output After updating to fedora kernel 4.12.5-300 from 4.11.11-300 screen is drawn with corrupt areas. For example login using KDE and start a new Konsole and start typing at the bash prompt to see the problem. Text is not drawn cleanly, it is overlayed with blobs that come and go. Also seen in PyQt apps and firefix. Problem is still present in 4.13.4-200.fc26.x86_64.

My guess is that the difference is due to enablement of acceleration? Not sure if that's when GP106 happened though. You could boot with nouveau.noaccel=1 to disable it. I've recently fixed a bug in mesa introduced in 17.2 which could maybe cause some of these issues. What version of mesa are you using? [commit b20bccbcacc6170cfc4f18332491131df5bac811 upstream.] "Overlayed with blobs" generally means either texture corruption or ... something else. Are you using the 'modesetting' DDX? If so, I strongly recommend using the 'nouveau' one.
nouveau.noaccel=1 seems to fix the problem. But your "modesetting" DDX comment made me dig into the Xorg config. I was using the modesetting DDX and added the following config: $ cat /etc/X11/xorg.conf.d/20-nouveau.conf Section "Device" Identifier "Nvidia card" Driver "nouveau" EndSection That also seems to fix the problem. I'm saying "seems" because I have not done a lot of testing. I will update this bug once I have made sure this is "user error" (no nouveau config). Oh and mesa is at 17.2.2-2.fc26.x86_64.
The problems are all gone. Please chalk this up to user error - did not configure Xorg to use the nouveau driver.

More like "distro error" -- "listened to the cacophony of people saying modesetting is the way to go". The real issue is that there's some issue in the GL, hence the display issues. Now they will be limited to applications that use GL [which sadly is "a lot" these days].
I raised this with fedora: https://bugzilla.redhat.com/show_bug.cgi?id=1483037 and have updated to comment that the wrong driver is might be used by default.
I wont recommend using/keeping the GP106 (GTX 1060). It cant ever run with free software: https://www.theregister.co.uk/2015/04/15/nvidia_gtx_900_linux_driver_roadbloack/ https://www.phoronix.com/scan.php?page=news_item&px=Nouveau-XDC2017 https://www.phoronix.com/scan.php?page=news_item&px=Nouveau-XDC2016-NVIDIA Sell this crappy GP102 card away and go away from nvidia. Nvidia died with the 780ti card. Its the last end-user card that can be used normaly. Everything else is in some countries even a legal problem. Because the manufacturer (nvidia) blocks the users from beeing able to boot the software they want on THEIR hardware - happyly illegal in some countries. Hopefully some layer would sue the heck out of nvidia so that they would have to release the private signing key or close their doors. Blocking the freedom of the users on such way should not be accepted by anyone.
