Unwanted Lines and Borders Appear on Spreadsheet

[plebsareneeded]

Here's an irritating issue that has come up in the past few days.

I have a spreadsheet with regular text and dates—no special formulas or formatting. When I double-click on a cell to edit the text directly, it leaves behind a strange border around the cell as well as a horizontal line above the cell that stretches across the spreadsheet. The border around the cell looks a little heavier on the bottom and right sides, which leads me to think it's some feature that I don't know about and can't find easily to deactivate.

The border and line appear on almost any cell I select but the will vanish if I try to adjust the width of the columns or rows or if I scroll far enough down that they are no longer visible. Also, if I switch my focus to another program and come back to Excel, these borders and lines will disappear as well after a time.

This is a real nuisance. Any suggestions? Thanks.

Welcome to the forum.

That sounds like either a hardware issue, or one of many rendering issues that seem to occur periodically with later versions of Excel. Are you using 2016?

In any event, I'd try turning off hardware acceleration in the Advanced section of Excel options.

I turned off hardware acceleration and restarted Excel but the problem remained. I'm using Professional Plus 2016. Weird.

Given that it has only just happened, I'd check what updates have been applied to your machine in the last few days.

Good point. I'll check with our IT team. I thought it was a mistake I made with the user settings. Thanks.

Chiming in to say that I've just had this bug start happening to me too within the past couple of days, as have a number of my collegues. Would love to find out what's causing it and if there's any way to fix it. Tried uninstalling and reinstalling office Professional Plus 2016 but the issue still persists.

Can you tell me which build number you have?

 

[hmyt~]

Sure, 16.0.4549.1000 32 Bit
