Having the "Use smooth scrolling" option unchecked in both Firefox and
Thunderbird seems to have fixed the 'wavy line' problem for me.
Thanks.
I'm guessing the wavy line that you describe is 'tearing' that appears
when the display is not synced to the framebuffer, i.e. "vsync". I
believe some of the graphics drivers are not even capable of vsync
currently in X11, but I'm not certain.

That sounds right. I just wasn't sure how to best put it into technical
terms.
Thanks.
