 I'm marking this as resolved.

 The original problem (with using the window for rendering when creating
 PPM files) is essentially a "cantfix".

 With the fixes to the code which uses GLX Pixmaps and pBuffers, you should
 only need to use the window on systems where no other option is available
 (and in that case, there is simply no solution; you just have to manually
 ensure that nothing occludes the window during rendering).
