--- Comment #10 from Ognian Tenchev <drJeckyll at Jeckyll.net> ---
OK - Thanks for explanation. 

But I still think that there is something broken. 

I switch back to SNA in xorg.conf and:

# SNA - before
cat /sys/kernel/debug/dri/0/i915_gem_objects
481 objects, 185946112 bytes
245 [241] objects, 248385536 [245698560] bytes in gtt
  0 [0] active objects, 0 [0] bytes
  245 [241] inactive objects, 248385536 [245698560] bytes
165 unbound objects, 60375040 bytes
36 purgeable objects, 25972736 bytes
23 pinned mappable objects, 24096768 bytes
35 fault mappable objects, 22155264 bytes
268435456 [268435456] gtt total

X: 479 objects, 185810944 bytes (0 active, 123117568 inactive, 60375040
unbound)
xfwm4: 0 objects, 0 bytes (0 active, 0 inactive, 0 unbound)

Then I start firefox and open this image:

# SNA - after
cat /sys/kernel/debug/dri/0/i915_gem_objects
362 objects, 208642048 bytes
57 [57] objects, 106934272 [106934272] bytes in gtt
  0 [0] active objects, 0 [0] bytes
  57 [57] inactive objects, 106934272 [106934272] bytes
127 unbound objects, 33849344 bytes
0 purgeable objects, 0 bytes
23 pinned mappable objects, 24096768 bytes
10 fault mappable objects, 41943040 bytes
268435456 [268435456] gtt total

X: 360 objects, 208506880 bytes (0 active, 43421696 inactive, 33849344 unbound)
xfwm4: 0 objects, 0 bytes (0 active, 0 inactive, 0 unbound)

Now I start to see artifacts on my screen. I will attach them in this bug.
before - LibreOffice normal menu before opening large image in firefox
after - same menu but after opening large image in firefox (missing background
on selected item)
afert2 - there are two rows of text bellow actual text on the bottom - Geany
editor :)
after3- buttons on LibreOffice dialog with strange borders ...

So something clearly broke after I open large image ...
