Why do row borders distort and rows seem to overlap one another when I scroll up or down a worksheet in Calc?

I have version 5.0.3.2, English. My operating system is Windows 10.

Menu/Tools/LIbreOffice calc/View - Visual Aids - Grid lines - Show on colored cells.

Thank you m.a.riosv for pointing me in the right direction! I actually needed to check “Helplines while moving”, so the whole path was:

Tools/Options/LibreOffice/View - Visual Aids - Helplines when moving

It has worked like a dream. Thanks again.

Thanks for your confirming, please if the answer has solved your question please tick the :heavy_check_mark:.
