Summary: [Windows] Dragged-out tab mini-windows appear blank when page is in accelerated compositing mode

Description Andy Estes 2012-02-12 16:11:13 PST
Steps to reproduce:

1) Go to http://www.apple.com/iphone/
2) Drag the tab out of the Safari window

Expected result:
The mini-window should contain a snapshot of the tab's contents.

Actual result:
The mini-window is blank.

I believe this also causes pixel test results of compositing tests to be blank on Windows. This blocks testing the accelerated part of <https://bugs.webkit.org/show_bug.cgi?id=77382>.
