Created attachment 193705 [details] Video showing the problem Suppose you have vertically merged cells and you add borders to them. If you have multiple such merged cells stacked vertically and start scrolling your document, you'll notice that the top border is not painted when the merged cell is only partially visible. To better understand the bug, see attached video.

Although I don't repro this on Windows with a recent 24.8 alpha (or, alternatively, I am not understanding the STR), there is a similar issue in tdf#160654 (scrolling horizontally instead of vertically), which I can repro on Windows.
