Public bug reported:
I'm using Ubuntu 12.10 (updated to current date of writing this report)
under 1440x900 resolution. I have indicator-appmenu removed, so in my
maximized terminal I see the menus below the main bar on the top.
I use the font "Ubuntu Mono" with size 12, other parameters set to
default. The cursor shape is Block.
The bug is that the last line of the terminal seems to be just a little
too low, somehow printing characters below a defined window or
something. The symptom of the bug is that in a maximized terminal, once
the cursor passes the middle column, it will leave artifacts behind on
the last line (one pixel width?) which doesn't get cleared up.
I cannot take a screenshot of this, because any refresh of the screen
(such as minimize and back, or the flash from Ubuntu's screenshot
program) makes the artifacts go away. However, I took a snapshot with a
camera and attached the image.
If I have a different terminal window size, such as when indicator-
appmenu is installed (so there is some more height available for the
terminal), this does not happen. Neither does it happen in an
unmaximized window. The reason being that unmaximized windows make the
height a multiple of the line height gnome-terminal likes, and in the
case of other window sizes because the calculated "last line" of the
terminal is luckily placed a bit higher than the bottom edge.
My suspicion is that when calculating how many lines fit in the given
height of the terminal, there is an off-by-one-pixel error.
