Description zaibatsu7 2016-08-17 02:21:39 UTC 
Hello. Using default Xubuntu 16.04 evince package. With relatively big pdf (books etc) - say, 500-1000 pages, scrolling becomes very laggy and sluggish after some hundreds of pages, so I have to scroll with arrows only. Tested with 1062-pages 'C# 5.0 in a Nutshell 5th' doc.

To reproduce:
 - open any big file;
 - scroll a bit - everything should be fine;
 - go to near-end;
 - try to scroll again.

Does this happen with or without thumbnails side bar opened?
Comment 2 zaibatsu7 2016-08-17 03:28:17 UTC 
In both cases the same. The way how to get rid is to turn off Continuous mode, but it doesn't makes sense in this case.
Comment 3 José Aliste 2016-08-17 04:14:46 UTC 
yeah... it's a new bug... No idea where to start looking at.
Comment 4 zaibatsu7 2016-08-17 04:37:10 UTC 
Seems whole doc scanned to current page on every scroll event or something like that. Just a guess.

+ as some kind of feature proposal: would be great not just invert colors but reduce contrast too, to prevent eye strain in dark environment.
