Description Oleg Atamanenko 2010-03-08 10:09:35 UTC 
Version:           0.10.1 (using 4.4.1 (KDE 4.4.1), Chakra)
Compiler:          gcc
OS:                Linux (i686) release 2.6.32-ARCH

Currently it is difficult to use scroll up/down using buttons 'page up' and 'page down' because pressing those buttons moves the whole screen.

And it causes the following situation:
If last line on the screen is not fully rendered (only half from top) and I press page up then okular scrolls down one screen and last line (which becomes first after scrolling) renders only bottom half so I'm unable to read that line and I have to press up and down.

See attached screenshots.

I suggest to detect incomplete rendered line and render it correctly. Maybe it will be much better to render previous 2-3 lines so user will not lose context of his reading.
