[Spice-devel] [PATCH spice-gtk] spice-widget: Fix rendering issue with X11 backend enabled

[Dunrong Huang]

bug on linux platform.

If X11 backend is enabled, app window will becomes while screen when draging it.
This bug can be reproduced easily:
compile spice-gtk using:
$ ./configure --with-gtk=2.0 --with-x11
$ make
$ gtk/spicy -h host -p port
