XFCE panel screenshot

This is clearly a regression because kernel 4.12.x worked just fine here and
all 4.13.x releases exhibit this problem.

I'm running XFCE under Fedora 27 (recently updated from 26 which also exhibited
this bug) without a compositing manager.

Upon logon XFCE panel icons are always broken in one way or another. If you
move any window above the panel then everything gets back to normal. Yet when
you run `xfce4-panel -r` glitches return.

Also this bug manifests itself in Firefox when you're scrolling. Text often
gets strange artifacts.

Here are relevant kernel messages:

Please confirm that you're using the nouveau ddx and not the modesetting ddx?
[Include your xorg log.]

Was acceleration working for you with the 4.12.x kernel? I don't really see
what would have changed in the kernel to affect this one way or the other.

We're now using the full BAR2 amount (bar/gf100: fix access to upper half of
BAR2)... Could be somehow different on GP10x?

I've no idea what I'm using. I have a default Fedora 27 installation without
Xorg.conf file or any configuration for kernel modules.

I'm not sure what you're talking about. I don't use any applications which use
3D acceleration and I've no idea if 2D acceleration is in use.

Er, no clue ;-)

[    42.818] (II) modeset(0): using drv /dev/dri/card0

You're using xf86-video-modesetting. Please switch to xf86-video-nouveau. This
would normally be the default, but I believe Fedora does something to break
that (on purpose). You should reach out to their support forums if you need
help unbreaking it. I believe an xorg.conf that forces nouveau to load will do
the trick, but I'm not sure.

BTW - 2d, 3d - it's all acceleration. And it either works or doesn't. If it
doesn't, then you're fully cpu-rendered for everything.

Font artifacts while scrolling in Firefox are still present even with correct
settings.

Firefox

I've noticed that it happens only with italic web fonts.

If you open the same web page for the second time the problem disappears.

If you cover the browser window and put it back into foreground the problem
disappears.

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.

This is reproducible under NVIDIA binary drivers as well.

In fact it's an X.org server bug.
