Bug Description
On Babbage 2.0, I get something like 60-80 pixels of black on the top pixel row of the screen, at the left hand edge. This is observable primarily when X is running, but I'm guessing it probably happens the rest of the time as well. This strip of pixels is permanent and X does not appear to be able to draw over it.
Often, but not always, there is also a black cell overlaying the top-left corner of the screen, coinciding with the black strip described in the previous paragraph. The cell appears to be the size of a text console character cell. If X draws over it (by animating the Applications menu for example), the black cell disappears for a fraction of a second and the reappears, as if the cell is being redrawn many times a second.
My best guess is that these problems are bugs in the framebuffer driver stack or possible hardware issues, but I've not been able to investigate further.
I don't know whether either of these issues affects Babbage 2.5.

I see it too, but only in the live session.
I suspect usplash/xsplash might be interfering.
