ah. When I examined the figure, I only noticed the "<0:57:39" at the
top of the screen. Reading your latest message, I notice the glitches
in the window's border area. I believe that's in the area set by
internalBorder (class BorderWidth)
and since it defaults to 2 pixels, is easily something that might be
overlooked in calculations - particularly if it's related to fonts which
draw outside their cell, and xterm's clipping doesn't go that far.
(I've seen this, but not often enough to have a scenario where it can
be reproduced...)
