Is this on Mac OS X using Cocoa Qt? There is a known bug with regards to QGLWidgets not properly initialized when they are invisible (e.g. in a scrollbar's invisible part) at the time of widget creation.

Might be related (this is not an issue however on Windows or Linux). Unfortunatelly this won't be fixed: "Out of scope". But the original bug reporter, Alan, mentioned a workaround, see issue above.

Cheers, Oliver
