I am sure this is a known problem, but looking on the archives didn't help, maybe I didn't come up with the right keywords, anyway... I am using OSG 2.4 (but the problem was already there since OSG 2.0) under both Win XP and Linux, with the Qt4 wrapper and when I resize the window to zero width or height and then restore it the content of the scene disappears (my program has 3d views that can be temprarily hidden/restored). This behaviour seem not to be related to the driver but to OSG since with OSG-based programs I get the same problem with nVidias as well as with ATIs, while other non-OSG-based programs don't show this problem.
I suspect that with a zero-area viewport something breaks into the culling mechanism or some division by zero mixes up some OSG internal state or matrix. Does anyone know how to fix or work around this? do I have to reset something once I detect a non-zero area viewport in my resize event handler?
