I just got the problem in 12.10 for the first time. I have a dual-screen setup at a Radeon HD 2600XT (I know). My main screen is horizontal, the secondary screen is vertical. This setup did work in 12.04. In 12.10 my GNOME Shell opens with a grey decorationless window on the left (see attached downscaled screenshot). I can use a context menu to copy the text in it out and into an editor, which reveals a localized version of the messages other users get. The fun thing is: the screen setup is 100% working - resolution, aspect, everything. But I still get the annoying window - and closing it isn't easy because there are no window decorations.

I can get either monitor to come on through either output extension but when trying to get both to work at the same time the graphics go crazy. Both displays are listed in GUI display manager--just don't come on as expected when changing display settings. I can get triple head to work with AMD Radeon 5000M video adapter (same software setup) but the displays go crazy when starting a virtual machine or Skype. FWIW, on the AMD Radeon HD 6470M system System Info states graphics as Intel® Sandybridge Mobile while on AMD Radeon 5000M graphics are listed as Gallium 0.4 on AMD REDWOOD. Any thoughts or advice welcome.
