Having upgraded x11-drivers/xf86-video-intel to version 2.21.7, I noticed that the Shmem field reported in /proc/meminfo keeps increasing until the whole system memory gets filled. Killing the X server resets this count to a normal value. After having masked recent upgrades and re-enabled them one by one, I found that the bug occurs only with this version installed (not present in 2.21.6 currently present in tree). By the way, the problem seems to happen regardless of the kernel kind (gentoo or hardened), xorg version (both 1.14.1 and 1.13.4 shows the same behavior). Reproducible: Always Steps to Reproduce: 1. Upgrade x11-drivers/xf86-video-intel to version 2.21.7 Actual Results: /proc/meminfo shows a Shmem increasing constantly for no apparent reason Expected Results: Stable memory consumption amber ~ #

Created attachment 348999 [details] emerge --info 2.21.7 works fine here. I have amd64/hardened and a Sandy Bridge i5 too. Maybe it's the UXA?... (I get some serious wrongness with SNA, a different kind of wrongness.) How long does it take for the shared mem to deplete completely?
On my machine, it eats around 4Mb/s. As I was using sna, I just gave a try and recompiled with -sna uxa and I don't observe this behavior in this mode.
Check with xrestop whether it is an application that causes runaway memory usage. If not, then please report this upstream at https://bugs.freedesktop.org/ and provide the link to the report here.

Okay, xrestop does not shows any hogging process. However, I was able to reproduce the problem with a minimum set of programs running. It happens when there is X + sna, xcompmgr and conky running. I attached a minimal conkyrc that triggers the bug. You can reproduce this with this set of commands $ X -ac -terminate :0 & $ DISPLAY=:0 xcompmgr &>/dev/null& $ DISPLAY=:0 conky &>/dev/null& Versions and useflags for these programs : app-admin/conky-1.9.0-r2 was built with the following: USE="X curl imlib lua lua-cairo lua-imlib math moc ncurses portmon truetype vim-syntax -apcupsd -audacious -debug -eve -hddtemp -iostats -mpd -nano-syntax (-nvidia) -rss -thinkpad -weather-metar -weather-xoap -wifi -xmms2" x11-misc/xcompmgr-1.1.6 was built with the following: USE="(multilib)" Should I still report that upstream or do you have any more insights ?
The problem could still be related to hardened, but that is not likely. So you can report upstream.
well not sure if need to open another bug for this one.. I encountered one problem with x11-drivers/xf86-video-intel-2.21.7 can't take proper screenshot with ksnapshot using capture mode -Rectangular Region -Freehand region Screen become black and mouse drawing the region to take a snapshot produce artefacts downgrading to =x11-drivers/xf86-video-intel-2.21.6 solved the problem ksnapshot-4.10.3
Created attachment 349096 [details] emerge --info
Looks like someone else was faster to report this upstream, who then fixed it in 2.21.8.
