I was of the impression that compositing should be faster with EXA. Except for this glitch, EXA on intel seems very stable otherwise...

It should indeed; the thing is, the way GLX_EXT_texture_from_pixmap is currently implemented with AIGLX, it actually tends to be faster with 2D acceleration disabled, which is what the XAA option achieves. If the patches I put up on http://people.freedesktop.org/~daenzer/aiglx-zero-copy-tfp/ were ported to the i915(tex) 3D driver, that should be much faster with EXA.

Sometimes I really wish I could code... Anyway, I noticed - after opening several windows - that compiz still was a bit slower than with the older driver. Not unusably so, just slightly annoyingly... I'm trying out xserver 1.3 + xf86-video-intel 2.0 now (contra my first post, all other packages are latest released, i.e. no git-version of anything), and compositing with compiz is too slow for everyday use now... I've tried both XAA + XAANoOffscreenPixmaps, as well as EXA. Is there any work around for this?

Ported to i915tex and pushed to the master branches. Hi ! I have the same trouble with xf86-video-2.2.1 on Archlinux and Compiz-Fusion. With the package 2.1.1, no problem, fluid and not CPU intensive. P200 Toshiba Laptop with 945GM. If you can help... Thanks 1 If this is still an issue with current versions of the intel drivers, please reassign to Driver/intel and select 'Reassign bug to default assignee and QA contact, and add Default CC of selected component'. |
