I don't have the hardware to try this, but I will look around.

In any case in the bug report in Launchpad there are all reports on
similar graphic cards, AFAIK, Bonaire + radeon.

Does the problem also occur on an Intel GPU using the Xorg modesetting
driver instead of the intel driver?

How I am I supposed to use EXA mode to disable glamor?

I just spent the last hour trying to do this unsuccessfully. Xorg 
-configure always fails with "Number of created screens does not match 
the number of detected devices", which seems to be a known issue. 
Manually creating the file causes Xorg to fail. All other attempts at 
modifying the config results in Xorg failing to start.

So, can you check whether the Xorg modesetting driver is used with that,
and whether it enables glamor acceleration? And if either is not true,
can you try forcing it in xorg.conf and see if you can reproduce the
problem then?

That's not what I meant. I'm interested in whether the problem occurs
with the nVidia GPU as well using the modesetting driver and glamor.

All you should need in /etc/X11/xorg.conf is something like:

Section "Device"
Identifier "Device0"
Driver "modesetting"
EndSection


However, it occurred to me that glamor might not work on a GTX 970
unless you're using very recent upstream snapshots of Mesa and the kernel.

Bug#821763: xserver-xorg-video-radeon: LibreOffice Preferences UI font corruption on AMD A6-1450 APU/Radeon HD 8250

[J Mo]

Package: xserver-xorg-video-radeon
Version: 1:7.7.0-1
Severity: normal

Example image:
http://jmomo.net/files/snapshot_LibreOffice_fonts_broken-2.png

Notice the blocks under "Menu" in the middle-right where letters should be in 
the UI.

The hardware is a Zotac ZBox CA320 which has a AMD A6-1450 APU (Radeon HD 8250).

I have been using the hardware for about two weeks now and this is the first 
graphical glitch I've seen, so this could be LibreOffice too. Let me know if 
yuo want me to refile on LibreOffice.

I pulled the SSD from this system and ran it on other hardware with a different 
(NVidia) GPU and the artifacts went away.

Looks like https://bugs.freedesktop.org/show_bug.cgi?id=63397 .

Which drivers were used on the Nvidia GPU? If it wasn't the nouveau
kernel driver and the Xorg modesetting driver, it would be interesting
if you could try that combination to see if it happens with that as
well. That could narrow down where the bug is.
