Screenshot of Display Problem when scrolling from bottom to top in 2-page mode
When writer is in 2-page mode, scrolling from top to bottom OK. But when scrolling from bottom to top, pages on the left are not displayed properly. Blocks of the pages are missing. See attached screenshot.
Also, when this happens, the zoom line on the bottom right hand of the page sometimes dissapears. It still works if the mouse is used as though it was there. It seems to dissapear at certain zoom sizes.
Zooming the page plus or minus refreshes it so it displays properly.
Windows7 64, Intel i-7 4800MQ, Intel HS Graphics 4600, Nvidia Quadro K610M
Have not seen this bug in earlier version of Libreoffice or in OO.
This problem does not occure in single page mode.
