Default Re: nvidia 256.52 xorg-server 1.9.0 performance regression

Hi folks,

I'm still experiencing this problem after upgrading 260.19.04 to 260.19.06; it sped things up a little bit but the scrolling issue in Firefox especially remains. It does appear that if I turn off antialiasing fonts completely and set Firefox to use the global smoothing setting (about:config, gfx.use_text_smoothing_setting) the scrolling becomes quick again after restarting the browser. While this works for now, it's obviously not a longterm solution. I'm running Compiz on the Ubuntu Maverick release candidate.

I've attached the output of nvidia-bug-report.sh; let me know if I can provide any further details.

Edit: gtkperf results (with font smoothing completely off):
