The direction that nvidia going its very coool i hope that they keep going this way also in GL 3 and 4
and there is a few 3d application that use gl 2.0 or 2.1 like Autodesk maya (i think) and Softimage , yes?
I just tried those drivers, but nvidia failed (again) to provide gradient acceleration to cairo.
As a result if your gtk theme is not *VERY* basic and you use vanilla cairo, you'll get a really slow scrolling when native widgets (buttons, input boxes) are displayed in the page.
Workarounds are to use an ugly gtk theme or to rely entirely on the cpu by patching cairo source.
For the record, nouveau or even ati drivers on a poor 9500se scrolls better.
System tested on; Nvidia 313.09 / Nvidia GT440 / AMD Phenom II 965 X4 / 16gig RAM / Archlinux 64bit / Cinnamon (built weekly from git)
that being said, if i can reproduce this issue, it would probably be worth reporting, or adding myself to your existing report (which i assume you have made, otherwise you are just wasting your breathe complaining here ;)).
As a side not to my earlier comment about the traces in dmesg; they have returned, so that bug still exists, although it isn't causing me issues...
Well this is cool... there's already an experimental compiz w/ support for the new GLX_EXT_buffer_age extension:
I may take a look, but i got sick of all of the nvidia problems with compiz and switched to KDE (which i couldn't get used too) and then settled on cinnamon, which is great and has a much better implementation of expo than compiz does. (compiz has had the same few ugly bugs for years and years - dragging/wrapping windows results in the workspace being drawn above the window, the window-edges/aliasing is terrible in not only expo, but also scale too).
But on the brightside, according to Sam's blog, that experimental ppa, has fixes for the long standing show-stopper of window-dragging (when using certain gl app, like xbmc) resulting in your whole desktop moving at a crawl (basically unusable). Which is one of the reasons i dropped compiz + the 'nvidia blank window' bug, which hasn't been fixed in the 1yr 1/2 that the bug report has existed ~ even though it makes using compiz with nvidia annoying.
I think in due time I'll give Cinnamon and maybe even Elementary a look. Unity is "okay" but some things are annoying and ugly.
Then install cairo-nvidiablob from aur and scroll it again.
For me, vanilla cairo is jerky with the blob, smooth with everything else, i just tried again.
