basically the culprit of bad performance of new cairo is due to we are missing this patch: http://repos.archlinux.org/wsvn/packages/cairo/trunk/cairo-1.10.0-buggy_gradients.patch here's a snipped from #gentoo-desktop: 11:07 < ssuominen> http://repos.archlinux.org/wsvn/packages/cairo/trunk/cairo-1.10.0-buggy_gradients.patch 11:08 < ssuominen> in case any of you is intrested... 11:09 * ssuominen doesnt know enough of it... 11:15 < Caster> just performance, or corruption as well? 11:22 < Ford_Prefect> o/ amigadave 11:23 < amigadave> \o Ford_Prefect 11:24 < amigadave> Ford_Prefect: zeenix complained that rygel was not in Gentoo :P 11:24 < amigadave> but he was happy that gupnp-dlna was there :) 11:25 < Ford_Prefect> :) Diego had some sort of ebuild prepared 11:25 < Ford_Prefect> But yeah, it's been on my todo list forever 11:26 < remi|work> ssuominen, FUCKING NAK ON THAT PATCH 11:26 < remi|work> 1) it's got "ubuntu" in it, big red flag right there 11:26 < ssuominen> hah 11:26 < remi|work> 2) it's looking at freakin' *proto #defines 11:27 < remi|work> #2 implies the patch is inherently broken 11:27 < ssuominen> The patch actually removes the "looks" 11:27 < ssuominen> notice the - as opposed to + 11:27 < remi|work> oh... right 11:28 < remi|work> [facepalm] 11:28 < ssuominen> so by default cairo is doing exactly the bad thing you described :P 11:28 < remi|work> well it's also basically disabling all hw support for gradients... 11:28 < remi|work> not that any driver gets that right ATM so... 11:29 < remi|work> sigh... cairo was indeed doing stupid shit 11:29 < remi|work> ssuominen, care to file a bug so we keep track of it? 11:30 < plaes> oh damn.. gtk3 really makes things complicated.. 11:30 < Ford_Prefect> What'd it do now? 11:32 < plaes> different deps :S
I discussed this with upstream cairo/pixman folks and the bottom line is that we should apply this patch if we want decent performance out of cairo. At least for now. Upstream is quite disappointed that almost no driver (except Intel, and it's not all great) properly supports hw gradients, EXA making things even harder. Will apply the patch tonight if no-one beats me to it. Cheers

Sorry about that. There was some DOS line endings in the patch. I've rerolled the patch and fixed that.
Thank you - that works :)
