A zip file that includes two images. One named Works that shows a display configuration that works normally, and one named Broken that does not.
When click-dragging the windowed inspector between two displays with the displays in a specific configuration, the window will jump vertically from underneath the cursor. This only appears to occur when the two displays are not top aligned.
Secondly: This does not seem to occur when grabbing a window edge, rather only when dragging from a region in the toolbar, inline with icons.
I've attached two images in a zip file that includes two images. One named Works that shows a display configuration that works as expected, and one named Broken that does not.
This should soon be fixed on future Mac OS X versions with the changes in bug 146324. Forward duping to that since that has a patch up!
