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.
