commit 648c8871c92727d7b6b16859f27f12266a06a16e breaks "xv" and "ImageMagick"

[Jeff Chua]

Commit 648c8871c92727d7b6b16859f27f12266a06a16e breaks "xv" and
"ImageMagick". Upon running the application, the window displays a
blank black window until certain mouse events triggered the window to
display correct contents. Reverting the commit solves the problem.
Tested on latest git pull.

Sorry it took so long to report as I've also updated everything else
and couldn't really pinpoint where the problem originated until
recently where I started using "xv" and "display" more often.

Thanks,
Jeff
