What we know

• Some draws of new windows do not make it to the screen
• Moving the new window fixes the problem
• Moving the window fixes the problem even if the firefox binary is paused
• I use 4 Spaces normally. When I'm on the first desktop, I can reproduce this

bug. When I'm on the second through fourth desktop, I can't.

• Sometimes we draw more than once

Reliable steps to reproduce from fresh boot
