If you minimize the Ren'Py window in the middle of a transition (like a dissolve), and then you un-minimize it, the game display will be totally gone; the Ren'Py window will become a hollow window.

The only way I found to get the display back was to resize the Ren'Py window. Otherwise, you'll either have to quit the game blind, or use Task Manager to close Ren'Py.

May or may not be related to this other bug: https://bugs.launchpad.net/bugs/802831 "Display bug when entering game menu screen during a transition."

A demonstration game is attached to this post; it's the same as the demonstration for the bug above: http://lemmasoft.renai.us/forums/viewtopic.php?f=8&t=10891

I observed this bug on a Windows 7 computer, using the Windows 7 Basic theme. I don't know if a similar effect happens on other OSes or configurations.
