Bug#860365: mutter: Graphical glitches on Intel GMA X4500 with SNA and Wayland

[Kevin Keijzer]

Other things I've tested that didn't help:

Updated the following packages to the versions in experimental:

- libegl1-mesa 17.0.3-1
- libgbm1 17.0.3-1
- libgl1-mesa-dri 17.0.3-1
- libgl1-mesa-glx 17.0.3-1
- libglapi-mesa 17.0.3-1
- libgles2-mesa 17.0.3-1
- libwayland-egl1-mesa 17.0.3-1

-- reverted back to stretch --


Updated the following packages to the versions in sid:

- gir1.2-mutter-3.0 3.22.4-1
- libmutter0i 3.22.4-1
- mutter 3.22.4-1
- mutter-common 3.22.4-1

-- reverted back to stretch --


Meanwhile, the system running stretch with UXA has not shown this issue
for over three days now. (Normally it happens every couple of minutes.)

/etc/X11/xorg.conf.d/20-intel.conf:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod" "uxa"
EndSection


I am uncertain if this happens on newer Intel GPU's as well, because I
don't have any. I may have some i945 boards with a GMA 950 that I could
test later.

What I have tested, is a GeForce GT220 with the nouveau driver on a G41
board. I could not reproduce this bug there.
