This is a bug in all nvidia-drivers newer than version 100.14.19. If you need more information, please refer to http://www.nvnews.net/vbulletin/showthread.php?t=104881 Either downgrade to nvidia-drivers-100.14.19 or don't run more than one X-session at once.
This is not suggestion. Suggestion is to fix nvidia-drivers, xorg-server, etc.
There's nothing about nvidia-drivers, Gentoo is able to fix as long as nvidia decides to keep their drivers closed-source. Bug nvidia if you want fixed drivers. There's no need to fix anything with xorg concerning this bug. The bug is in nvidia-drivers and nvidia is the only institution who can fix it.
