nvidia-270.30, xorg-server- & resizing + ongoing issue
1 Attachment(s)
The 260.* drivers had issues with 3d app (or 2D apps that indirectly linked to libGL: eg gvim -> cairo -> libGL resulting in gvim issues...)

later 260.* version improved the situation BUT did not completely remove 3D app issues with these drivers.
Likewise the 270.* line is not immune to this.

I play HeroesOfNewerth a fair amount and the last drivers that were problem-free were the 256.* drivers
early 260.* I would crash a couple of times a game
later 260.* and 270.* I would crash every other game

UNLESS: I launch HoN in a new Xserver:

newx() { DISPLAY=:1.0; xinit $* -- :1; }; /opt/HoN/hon.sh
Then via ctrl-alt-F7,8 I can switch between desktop and HoN without crashing.

Prior to this I was able to track down the crashes occurred whenever there was some form of 2D:3D transition. Be it the initial load screen -> map or if there is some form of OSD popup (libnotify from say exaile, skype [the skype trigger was the one that made me really look into this and force some libnotify events])

example crashlog from hon.x86_64

Again nvidia drivers and pthreads

Onto newer issues. Since running hon in a separate xsession (and thus no overlay from any OCD's occur) I have been running a composite desktop via xcompmgr for a bit more shiny to my openbox.
Problem is a nasty bug has occured with nvidia-270.30 + xorg-server-1.10...
If I go to resize a simple terminal the entire system locks up (and the display gets corrupted). I can just about ssh in BUT the system will not respond to system calls like shutdown et al.

Attached is the required nvidia bug report:
