Enormous Xorg memory leaking

Graphics / Linux Linux
1

Gentoo x86-64 system, Linux kernel 3.15.0, xorg-server-1.15.1, compiz-0.8.9

On nvidia-dirvers-337.25|340.17 the X process increase his memory consuming from ~35 MiB at the morning to 600-700 MiB at the evening. The system uses as a desktop with compiz (3D effect), Firefox (+Adobe Flash) and music/movies (xv video output). On nvidia-drivers-334.21 or on Linux kernels <3.15.0 the memory consuming is normal.

How to fix the problem?

I deleted some options from xorg config:

#	Option "AIGLX" "True"
#      	Option "BackingStore" "True"
#      	Option "DamageEvents" "True"
#      	Option "UseEvents" "False"
#      	Option "Coolbits" "1"
#      	Option "AddARGBGLXVisuals" "True"
#      	Option "XAANoOffscreenPixmaps" "True"
#      	Option "DisableGLXRootCliping" "True"
#      	Option "DRI" "True

and memory leaks are gone. Thank you!
