            Bug ID: 95413
           Summary: Oversaturation + Artifacts on screen refresh with
                    Redwood GPU
           Product: Mesa
           Version: 11.2
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: sawyerbergeron@gmail.com
        QA Contact: dri-devel@lists.freedesktop.org

In any compositor (XRender still affected, but to lesser degree) the screen
first appears somewhat oversaturated/of too high contrast, but on each
subsequent screen redraw the entire screen becomes less and less possible to
decipher until it becomes 2 bit black and white for every part of the screen
except for the areas that were most recently refreshed (while other parts of
the screen were redrawn, even if not refreshed.)

This bug occurs in Gnome 3, Plasma (4 and 5), and Unity, though it has no
effect on non X-sessions, nor does it appear to affect login screens (sddm,
gdm, or lightdm). Sessions composited using XRender are oversaturated/have too
high a contrast and are oddly colored, but do not exhibit increasing
saturation/contrast issues on redraw. OpenGL 2/3 are worst using GXL, though
OpenGL 3 with EGL is sometimes somewhat better (though far worse than XRender.)

For a graphics card, I use a FirePro v4800 (based on Redwood XT, I believe) 

If a screenshot would help, please let me know so I can post one

Please attach your xorg log, glxinfo output, and dmesg output.  Also what
versions of mesa, ddx, xserver, and kernel are you running?

Created attachment 123798
  --> https://bugs.freedesktop.org/attachment.cgi?id=123798&action=edit
1st file of those requested

Uname -r returns "4.4.0-22-generic"
X -version returns "1.18.3"
I have no idea how to check ddx, but if necessary I can with instruction
(probably)

Here are the files you requested

It would appear that there was a small issue regarding the card--there was some
cat fur blocking the fan from spinning at full speed, and something was causing
the motor to not compensate for that resistance. The card ended up getting
fairly hot during operation, and it appears after cleaning the card that it is
operating normally now. Sorry for the inconvenience this oversight on my part
caused.
