Bug ID: 341945
Summary: Wrong rendering with scrolling in PDF
Product: okular
Version: 0.19.3
Platform: MacPorts Packages
OS: OS X
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: PDF backend
Assignee: okular-devel@kde.org
Reporter: ni...@macports.org
When scrolling down in a pdf document, streaks appear in the document, as if
the page was not refreshed properly.
The issue was originally reported in https://trac.macports.org/ticket/45910,
where a screen capture of the issue is also given.
I noticed that the rendering problem can be corrected by unzooming/zooming,
pointing to a refreshing problem.
It also seems that the problem specially occurs when using scrolling with the
trackpad, but not with an external mouse.
This was primarily tested with version 0.19.3 (KDE 4.13.3), but the problem is
also present in KDE 4.14.3 according to my tests.
Reproducible: Always
Steps to Reproduce:
1. Open PDF document
2. Scroll down with trackpad
Actual Results:
Streaks appear in the document
Expected Results:
The pdf should render properly
