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.


Version:
LibreOffice 5


How reproducible:
Take a document with more than 1 page. Visualize it with a zoom that is wider than page width. Scroll quickly up and down


Additional info: 
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

The same thing happens here, with or without hardware acceleration and on both 32 and 64bit machines.

Relevant Version:
=================
libreoffice-5.0.4.2-3.fc23

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 ?

Comment 4 Cornelia Pfeffer 2016-01-27 15:41:54 UTC
desktop env. MATE

obviously in family we have all the same, and it happens to all of us

Comment 5 Cornelia Pfeffer 2016-01-28 16:08:02 UTC
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

Comment 6 Caolan McNamara 2016-11-11 15:26:00 UTC
can't reproduce it, so can't fix it unfortunately. I can only hope that an upgrade to e.g. f24 improves matters.
