After dragging a tab outside the main browser window I saw areas of the UI get blacked out (will attach screenshots). Dragging the tab back to the main window showed a different blackout symptom. Dragging the tab back to its own window resulted in everything being corrected.
FWIW, I am using a Macbook Pro (Retina, 13-inch, Late 2013) with OS X 10.11.1 Beta (15B30a) and Firefox Nightly 44.0a1. I have connected a Dell U2410 1080p monitor via Thunderbolt/HDMI and all Firefox windows are on this second screen.
As of yet this issue is not reproducible.
Steps:
1) Have one Firefox window open with multiple tabs, in my case:
> Fastmail (pinned), Mozilla Wiki (pinned), IRCCloud (pinned), MDN, Mozilla Wiki, Mozilla Wiki, QMO, Google Docs
2) Move the window to a secondary monitor, in my case:
> Dell U2410 @ 1920x1080 connected via Thunderbolt:HDMI adapter
3) Drag the Google docs tab to the desktop
> Google docs tab opens in its own window (see screenshot A)
4) Drag the Google docs tab back to the main window
> Google docs tab returns to the main window (see screenshot B)
5) Drag the Google docs tab back to the desktop
> Google docs tab opens in its own window without issue
Result:
Black screen issues as described above and illustrated in the screenshots.
Expected Result:
No black screen issues should be present.
