PDF file to reproduce the bug
While browsing a PDF document, when I scroll to the end of the first page and
see the second page, the first page that I have just pass over suddenly starts
being rendered as the second page. So I begin to see *two of the second pages*.
This is the casae for some of my pdf files, but happens everytime when I try a
problematic PDF file.
To explain the bug better, I have prepared a screencast here[1]. And after my
git bisect, I have understood that guilty commit is:
commit a73e7ff0186176bc82cd3ae1432c054c1fd3aebd

xlib: Simplify source creation by use of map-to-image
We were open-coding the functionality of map-to-image inside the source
creation routines. so refactor to actually use map-to-image instead.
Signed-off-by: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>>
Before this commit, everything works well. By the way I'm using evince
3.6.0-0ubuntu2 and poppler 0.20.4-0ubuntu1.1.
PDF to reproduce the bug, is attached.
Regards (and thank you very much for the Intel SNA implementation).
