Since the last post, I have tried the following to resolve the
CPU/Memory problem:
I added XAANoOffscreenPixmaps but it did not resolve the high CPU
consumption.
I added epdfViewer and Xpdf viewer. I had the same high CPU usage in
epdfViewer as in Evince, but I did not have the same problem in
I have Ubuntu 7.10 on fresh install with Evince 2.20.1. My CPU goes up
to 50-80% when I use the scroll bar.
Please let me know what kind of information you require. I have not
submitted a bug previously. I reloaded Evince and I did download the bug
report package with it. Gnome launched an
I confirm the fix. but just a question: if firefox has a similar
problem, that gets fixed using the same XAANoOFfscreenPixmaps
workaround, does this mean that it has the same problem?
(firefox uses CAIRO_FORMAT_ARGB32)
thanks

that might be the same problem, I don't know cairo enough to comment on
that though, you might want to contact upstream about the issue

I'm having the same problem (evince working badly on a laptop with
1400x1050 display and a Radeon). What are the negatives of
XAANoOffscreenPixmaps if any, and is there a real fix that will go into
Gutsy eventually?
--
[gutsy] very hi cpu usage when scrolling pdf
I don't know if it goes into gutsy.
I don't see any performance regression using this option. but:
- I don't run compiz because it is too slow for now
- I don't run games
please tell us your results!

This seems somewhat better in the current gutsy (maybe? or maybe it's
just because I'm looking at a different pdf?)

Me too on gutsy on nv driver. Scrolling, resizing, window movement,
changing pages, switching windows etc. is painfully slow (each step
takes some 5 seconds). That didn't happen in feisty for me either (on
the same hardware and drivers).

I'm seeing this too with a Radeon R250 [Mobility FireGL 9000] both in
initially rendering pages and changing pages. Moving windows around
does not seem to be affected (as one of the upstream bugs suggests.)

It seems that the bug report about cairo is quite old and unfixed...
This will probably mean that it will not be fixed. Is there a way to
temporary disable cairo in evince, so that I can view my pdfs?
This will be a big problem for people who has an r300 card

the easy workaround is to use evince 0.8 until the bug get fixed which
will be before gutsy becomes stable

example? Do you use a sidebar?

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?
