demonstration of the problem

Scrolling via page up/down is extremely slow in 1.10.1. Downgrading to 1.10.0 fixes the issue.


STEPS TO REPRODUCE

1. Open any PDF
2. Hold page down


OBSERVED RESULT

The document scrolls slower than when you hold cursor up/down.


EXPECTED RESULT

The document scrolls very quickly. Like in 1.10.0.


SOFTWARE/OS VERSIONS

Arch Linux


ADDITIONAL INFORMATION

In the attached video I first hold cursor down to scroll downwards. Then I hold page up to scroll upwards.

Whenever you fix one thing, another thing breaks :'(

AFAIK this has been fixed by allowing repeated scroll events.
