I believe those extra pixels at the bottom and right borders are what make my auto-hide Win7 task bar non un-hide when there's a maximized Nightly window is the top most window. I suspect it is the result of some interaction of Win7 changing to basic and back to aero when doing an screen sharing session on Microsoft Office Communicator
Another screen capture of the mysterious border.

It's a bit harder to see, but the double border at the bottom and right are also visible on door hanger.

Easier to see on a clearer background.

Jim, do you have any idea what might be causing this?

Actually, the door hanger bug is different - that's a drop shadow applied to a window that shouldn't have one.
Bas, didn't we do something weird for secondary monitors w/D2D that might be playing into this?
The exact specs in case they're relevant: Dell Latitude E6420[1] with a Dell E177FP monitor[2] attached. [1] http://www.dell.com/us/enterprise/p/latitude-e6420/pd [2] http://support.dell.com/support/edocs/monitors/E177FP/en/ug/about.htm#Specifioications

I've now spotted a bogus border on the middle click scroll indicator too, see http://i.imm.io/GAql.png Is this the same bug or a different one?

¡Hola Bas!

So I no longer have access to the system where this used to occur, but on a similar setup I now see https://bugzilla.mozilla.org/show_bug.cgi?id=1609129

Do you believe that one might be the same underlying cause, please?

¡Gracias!
Alex
