Arora displays a white square on some Flash video loads

It's possible this is actually a QtWebKit bug (this bug has similar symptoms but is fixed https://bugs.webkit.org/show_bug.cgi?id=25053 ). The first Flash video loaded does not isplay and instead you get a white box where the video should bug. Should investigate whether this is our fault in the first place.

The experimental 64-bit Flash plugin seems to work reasonable fine (at least, it loads). So perhaps it's nspluginwrapper's fault. Though one telling thing was that it prints out

(:21572): Gdk-CRITICAL **: IA__gdk_window_get_origin: assertion `GDK_IS_WINDOW (window)' failed

(:21572): Gdk-WARNING **: /build/buildd/gtk+2.0-2.22.0/gdk/x11/gdkdrawable-x11.c:952 drawable is not a pixmap or window

It's at least not as simple as NPP_SetWindow is not flushing Xlib buffers.
