All of a sudden I have thin maybe 1 px. wide horizontal lines of various colors running through several apps ie. Firefox, MS Word, my Mail app and several others. I'm on a MacPro.

Any suggestions?

Inverter board or video card is dying. I have this on a couple of older iMacs. If it's under warranty you'll want to get it fixed.
