Evince blanks some pages, and keeps that in cache.

Thanks for your bug. Does it happen on some particular document? Does it hang
when that happen? Could you do a screenshot of the issue?

(In reply to comment #1)

It happened a few times in the last days. The program didn't hang, I could
scroll through the document. It was not in a specific document. I also used the
'reload' from the menu, but the blank page stayed that way.

I could not find a way to trigger it, so I have no screenschot. However I saw
that a page update is occasionally slower than normal.

One way to trigger it: Select a few characters or words with the mouse, and
select reload from the menu. Most of the page will be blanked and sometimes
evince will crash. I think there are other ways to blank a page, but I haven't
found those.

The crashes seem to be already mentioned in
http://bugzilla.ubuntu.com/show_bug.cgi?id=16226 and
http://bugzilla.ubuntu.com/show_bug.cgi?id=14032 - could you try to get a back
trace (the bug buddy dialog), so we could compare the output?

I hope this is what you asked for. But this is when evice actually crashes. Most
of the time when a page is blanked, it doesn't crash.

The crash on reload is fixed, do you still have the blank page issue?

(In reply to comment #6)

I have now evince 0.4.0-0ubuntu4, and tried to install the 0.4.0-1ubuntu4 with
dpkg, but that was not possible, because it needs a number of newer dependencies.

Sorry, but I don't know how to test it right now.

Were you able to upgrade to Dapper to try it there?

I tried evince in Dapper. The known problem (blanking a page when selecting something) is gone. Evince is also more responsive.

The problem I reported was slightly different (opening other pdf's, and doing a lot of other things), but I was never able to reproduce it. I guess it is due to the same bug, and I assume it has gone also.

This bug can be closed.
Thanks.

jdo.

Thanks for following up.

I am using Ubuntu 18.04 and most of the content of pdf files are not shown. I as a bypass upload those docs to Google Drive and it opens files without any hitch. It is the same with Okular, xpdf and Atril too.
