My Monitor goes black for a few seconds intermitetly

I have had this issue for the last few months and I thought it was a hardware issue but today I had the channel settings window open (clicking on the E button of the track) and it suddenly started doing it a lot and I realized it’s likely a software issue. It never happens when Cubase is not open. I only use this computer as my daw. It seems to happen when I zoom into all the tracks or if I have the tracks squeezed down as small as it can go.

Today I was zoomed in about four times and had a channel setting window open and it was bordering on flickering.

Has anyone had this issue?
