Hello, cairo 1.10 update introduces a terrible performance hit and other bugs for at least nvidia users. Workspace switching takes whole seconds, window scrolling tears and jumps, some applications take forever to just redraw, all depressed GTK buttons are drawn few pixels off, and this is probably just the start. Happens both with and without GL backend enabled. Downgrading to cairo-1.8.10_1,1 returns everything back to normal, could anyone else confirm? On related note, this might be of some importance, see further in the thread: http://www.nvnews.net/vbulletin/showthread.php?t=156885 Excerpts: "It seems cairo 1.10 causes the NVIDIA driver to hit lots of CPU fallback code. Using 1.8 returns performance back to normal on all fronts." "Fedora's cairo doesn't include cairo-1.10.0-buggy_gradients.patch, so file a bug with Fedora's bugzilla." Anyway, I didn't test the mentioned patch yet, as I need a working system atm, but planning to get to it eventually, if nobody else checks/confirms sooner. m. -- Michal Varga, Stonehenge (Gmail account)
