Vertical Line Cropping

In using my standard documents, I've encountered a visual bug where occasionally the lines of text are cropped vertically.

This relates (most likely) to my bug 48851. I've done a full wipe and upgraded to Win 8.1 x64.

This same visual corruption has happened has happened twice (so far) opening the same file. Once it was only a section of lines. The 2nd time, it was more widespread. I've had it visually change the spacing of the lines where extra space was added between each of the bullet points (my style has it set to no spacing). So sometimes, it reduces vertical spacing, and sometimes it increases it.

There is no data corruption involved.

Yes scrolling fast through a document can sometimes remove sections of text, but a simple alt+tab twice can fix this issue. Can you confirm this?

This was not during scrolling. This was during static viewing. It is a random corruption, so I'll check alt-tab when it happens next.

I have come across a number of bugs about vertical line cropping including bug 79602 and bug 78600, and all of these are simply a redrawing issue which can easily be remedied by libreoffice refreshes its display, with alt+tab being one of such solutions. I look forward to your findings and if i'm mistaken about your bug, please do provide some steps to reproduce it and ideally a sample document as well and i'll try my best to locate the problem.
