The best I can get is VERY rarely, the very top line and only that line will flicker in your test scenario. By very rarely, that means that after moving over a couple hundred nicks/links, it happens once and then I have to go over a couple hundred more to get it to do it again. This is true no matter how fast I move the mouse.
That being said, it does show that there is a problem. However, it still affects certain people far more than others. It happens so rarely here and only on one line that it's not even remotely noticeable unless you're trying to find it. For others, it's apparently noticeable all of the time. The reason for it affecting some more than others comes down most likely to hardware or software that is specific to their system. mIRC may trigger it, but something else is causing the wide range of effects.
Btw, Khaled does read every topic in the bugs forum. You don't really need to send him messages to tell him to read a topic.
