could the people getting "white canvases" please get in touch to test a patch ?
Basically, the idea is to check if FBO setup failed and try some more conservative alternatives like pbuffers or ARBs instead.
We can use PIXEL_BUFFER_RTT or PIXEL_BUFFER instead of FRAME_BUFFER_OBJECT: http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2007-November/004790.html
Given that we're going to use Canvas in more and more placed, including the GUI, it would seem like a good idea to get this sorted obviously.
On the other hand, it is hard to troubleshoot this without being affected by the problem yourself :-)
it's not a new  problem: http://www.mail-archive.com/flightgear-devel%40lists.sourceforge.net/msg20103.html<ref>{{cite web
