The bug has been opened on https://bugs.launchpad.net/ubuntu/+source/evince/+bug/122786 "Binary package hint: evince I'm using gutsy, and I have evince 0.9.1-0ubuntu1. I notice a very hi cpu usage in this version of evince. When scrolling, and when moving a small window (for instance a terminal) over evince with a open pdf. This makes evince bad because it is too slow to use! ... http://launchpadlibrarian.net/8228961/01%20-%20IntroCorsoNew.pdf Yes it happens with all pdfs! here's an example. If a sidebar is the bar that opens when pressing F9, no. But it happens also when it is enabled. It happens in al "view" modes: fullscreen, continuous, dual... Could it be a graphic driver error? P.s. I have a mobility radeon 9700. I use the default driver"
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
