Version: (using Devel) OS: Linux Installed from: Compiled sources At high zoom levels, when adjusting the zoom level, Okular first draws a white page, "erasing" the previously rendered page, before rendering the actual result. This seems useless, and distracting. This is very strange: I'm at 200% zoom level. I zoom up to 250%. Good: no white page rendered. I zoom up to 300%. Good: no white page rendered. I zoom up to 350%. BAD: WHITE PAGE RENDERED I zoom down to 300%. BAD: WHITE PAGE RENDERED I zoom down to 250%. BAD: WHITE PAGE RENDERED I zoom down to 200%. Good: no white page rendered. Just a wild guess, does this per chance happen whenever Okular has to re-allocate a buffer?
The same thing than bug 209632 *** This bug has been marked as a duplicate of bug 209632 ***
