[osg-users] Open Scene Graph 3.4.0 has bug when using two monitor setup

[Robert Osfield]

Hi Thomas,

Only see the osgviewer.zip.002, was there an .001.

I'm a bit perplexed by needing to zip a stack trace up. I work predominatly
under Linux so Windows specific files are far less useful than straight
text outputs for things like stack traces.

Aside for the stack trace issues, one thing you could try is running the
osgviewer SingleThreaded. i.e.

  osgviewer --SingleThreaded cow.osgt

Robert.
