all cell lines not visable, have to guess at locations

just loaded lates Linux Mint and when accessing libre office calc, the lines on the cells show up intermittently, no rhime or reason for them showing or not showing, same options as in Ubuntu, which works just fine, how do I make all lines be visible? I tried reinstalling calc and still have same problem

have determined that the video card was the problem, updated bios, new computer with bad bios

I would check
Tools > Options and then

changing option in tools to show on colored cells did not work, anymore things I might try?
