From Jay Berkenbilt on Bug 2401.

Browse Source 
An Ubuntu user noticed that tiffgt was not appropriately calling glFlush(),
which was causing tiffgt to open blank windows in some cases.  I'm not sure
what the cases are, but my system happened to be one that saw blank windows,
and the one-line fix the user provided was sufficient to solve it in my case.
