i really doubt scrolling cpu usage is a poppler problem, i'd say it's more an evince bug, but i'll leave evince developers to comment it's not really scrolling specific, it takes several second to render a page when switching hmm, I can't reproduce the problem with evince. But if the problem is when redrawing once the page is already rendered, it's not a rendering problem. Is it reproducible for you Sebastien? It's happening with the cairo and the splash backends, switching pages takes almost all the CPU for a few seconds. Could be an xorg bug though, according to sysprof it's spending almost all the CPU in /usr/bin/X (though there is no detail). Switching between windows is also slow when evince is opened, looks like it's doing something heavy for the video that doesn't happen using an evince 0.8.1 binary on the same installation, looks like an evince bug I've opened http://bugzilla.gnome.org/show_bug.cgi?id=453123 |
