Losing context in continuous mode

Asked by Ildar Nizamov

Version 0.4.7
Reading pdf in single page + continuous mode. Apps bottom edge split last string at two parts, you see it's top part. "Skip forward" action (PageDown) push you exactly at bottop edge and now you see only bottom part of string, but never a whole line. Skip backward behaves the same. I've duct taped it with:

Hello Ildar,

I think the behaviour you describe is the default for all scrolled views in Qt and I would prefer not to get even more intrusive with this. Also in this particular case, I think a simple workaround would be to scroll up/down after jumping forward/backward a whole screen you just continuous scroll instead of jumping whole screens.

Best regards, Adam.
