Re: nvidia 256.52 xorg-server 1.9.0 performance regression
+1 for this. Most applications are okay, but ncurses apps (which I use heavily) are very slow to redraw. There's a noticeable top to bottom screen wipe. Plain terminal sessions (I use urxvt) appear to be unaffected. glxgears shows no choppiness and gtk applications such as Chromium seem to be functioning normally as well.
I use xcompmgr for transparency effects only. Disabling it and/or the compositing extensions has no noticeable effect.
I've attached a full bug report log.
