Hello,

I'm building a Performer application where the graphics window is contained
within a shell constructed using Rapidapp (with the GL drawing area
widget). I'm having problems constructing an overlay plane within the
pfPipeWindow. For some reason, I'm unable to configure the frame buffer of
the overlay window properly, and I can't get the colors I want to appear
correctly. The funny thing is, if I don't attach the pipewindow to the GL
drawing area, the overlay is configured correctly. The reason I'm using
the GL drawing area is that I want to use the functionality offered by
VkPopupMenus. There's no obvious way to use them with a conventional
pfPipeWindow.

Any ideas?

Thanks!
