Thanks for the testcase! I tried it out and see no red line on my system here (intel drivers) at 1024x768. And OTOH I cannot see why this would cause a red line to appear (esp assuming test-perspective is correct) :/
Could you log this as a bug on bugzilla so we track it better. I will try it out on nvidia in the week.
