            Bug ID: 91445
           Summary: Thick black borders around windows with Ubuntu
           Product: Mesa
           Version: 10.6
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Drivers/DRI/nouveau

what I see on Ubuntu 15.04

When installing oibaf ppa mesa 10.7.0devel, and also xorg edgers mesa 10.6.x, 
on all Nvidia GPUs I've checked (GT210, GT560, GT610, GT640),

all windows show a thick black border, having always the same quantized size
(could be power of 2), instead of window border elements.

Attaching image and boot, kernel and xorg log.
I am available to provide further log/traces if necessary.

Mauro

Are you using xf86-video-nouveau from git? That will have enabled DRI3 which is
known to have issues.

Can you provide your xorg log?

oibaf ppa does install
xserver-xorg-video-nouveau (1:1.0.11+git1507150732.5212db~gd~v)

while xorg-edgers ppa installs
xserver-xorg-video-nouveau
(1:1.0.11+git20150723.5212dbd7-0ubuntu0sarvatt~vivid)

I will check if forcing xserver-xorg-video-nouveau (1:1.0.11-1ubuntu2build1) 
is solving the problem.

Thanks a lot for your information
Mauro

Hi,

I've checked with both xorg-edgers and oibaf PPA drivers
and forcing the stable version of xserver-xorg-video-nouveau is solving the
black borders problem.

[on Ununtu 15.04]
sudo apt-get install xserver-xorg-video-nouveau=1:1.0.11-1ubuntu2build1


Thanks a lot, these xorg artifacts were bugging me since weeks
