Hello, Since I switched to cairo 1.2.0 + gtk 2.10, the performance on rendering has visually decreased. there are a lot of slowdows when gtk widgets need to be redrawn. I know you're waiting for numbers to compare performances, but I can't as I didn't performed benchmark before to switch from 2.8 + cairo 1.0.x. Anyway I'll happy to provide you numbers if you give me some hints on how to do so. Thanks
This is probably a dup of a bug that is fixed now. Can you try with latest git version? We were Xflushing where we didn't need to.
Specifically, here is the commit of interest: http://gitweb.freedesktop.org/?p=cairo;a=commit;h=b7191885c88068dad57d68ced69a752d1162b12c So if you don't want to try checking cairo out of git, you can use the 1.2.0 source code of cairo and apply the above patch, (just click on commitdiff, then plain to get the raw patch). Or you could wait for cairo 1.2.2 which will be appearing soon with the above patch in place. It really does help the xlib backend get right back up to its old speed again. -Carl
