corrupted visualization after scrolling
When I scroll a document up and down, the visualization of the text gets corrupted. Normally I have a zoom visualization, because I don't see too well. When I put visualization at "page width", the problem does not occur, only when the visualization is a bigger zoom.
Take a document with more than 1 page. Visualize it with a zoom that is wider than page width. Scroll quickly up and down
when you make some other operation, like going on another desktop and turning back, the visualization is ok again. When you scroll again, it is again corrupted.
I attach a screenshot with corrupted visualization after scrolling and after that a screenshot with perfect visualization using page width

when zoom = page width, the problem non occures
The same thing happens here, with or without hardware acceleration and on both 32 and 64bit machines.
This is the only report like this wrt corruption on scrolling. so it doesn't appear to be a common problem. What desktop env are you using there ?
desktop env. MATE
obviously in family we have all the same, and it happens to all of us
today we found out that if you select in LibreOffice - Instruments - Options - Visualization "use OpenGL for all rendering" (sorry if it's a bit different in english but I have the italian version and I'm only trying to translate...), there is no corruption when scrolling
can't reproduce it, so can't fix it unfortunately. I can only hope that an upgrade to e.g. f24 improves matters.
