This has been a problem at least in the last two releases (or two years) of ZSNES for me. It happens on both of my computers (GeForce 440MX and GeForce 6800GT). Here's what I mean by uneven scanlines --

It happens starting at resolutions 800x600 and above -- the image above is at 1024x768. I have fiddled with my graphics cards settings to no avail.
Obviously, the easy fix is to play in a low res or use the nicer filters. I don't mind doing so -- and with my current rig, I can. I just wanted to report this bug if it had not been made apparent by others.[/url]
