Yep sorry. I was having some (other) issue where text was not rendered when I had enabled shadows, so I was messing with osgViewer.cpp copying sample code from osgShadow there.
The example that reveals the issue at shutdown is plainly osgShadow.cpp Output: osgshadow.exe --window 0 0 1024 768 FOV is 29.1484 Error: OpenGL version test failed, requires valid graphics context. And a crasch. Interestingly only if you first move the camera (left mouse move) in the graphics window. If you do not interact with the scene, it only show the error message. /Anders On Thu, Feb 4, 2016 at 11:57 AM, Robert Osfield <robert.osfi...@gmail.com> wrote: > Hi Anders, > > There is a new mechanism for managing clean up of GL objects, which in > theory should help improve management of lifetimes of GL objects. > > The warning suggests that something is try to do GL call after the > context is cleaned up, I don't know yet if this is a bug in the new > code or whether the new code is just revealling an old bug elsewhere. > > Could you be more specific of how to reproduce the problem as there > isn't an --ssm option supported by the osgviewer example. > > Robert. > > > On 4 February 2016 at 09:05, Anders Backman <ande...@cs.umu.se> wrote: > > Hi all. > > > > Trying OSG 3.5.1 and I have started to get some problems with objects > > (osg::Program/osg::Shaders etc.) being de-allocated after context is > > destroyed: > > > > Error: OpenGL version test failed, requires valid graphics context. > > > > > > Sometime it crasches sometimes it just print the warning. > > > > I can reproduce it with osgViewer --ssm > > > > The only solution so far has been to keep a static reference to the > camera > > in the scene, which feels a lot like a hack. > > The same code worked in 3.4.0.
