Description Alex 2013-02-24 07:50:24 UTC 
Xorg process eats about 200Mb and more after some time of system using (with sna acceleration, it is ok with uxa). 

GPU HD4000, Ivy Bridge.

driver v. 2.21.3
kernel v. 3.7.9
Comment 1 Chris Wilson 2013-02-24 08:56:05 UTC 
Note that memory is accounted differently between UXA and SNA. All buffer allocated by UXA are invisible to top, whereas SNA uses standard CPU mmaps which do get accounted to the process. If you pay close attention you will notice that SNA uses far fewer buffers than UXA.

top is not accurate here. The numbers that matter are /sys/kernel/debug/dri/0/i915_gem_objects

I'm very sorry. I found the real cause of the problem. It is qbittorent app. I will close this bug.
