Hi Raymond,
I get a black window on my 2nd monitor when I use osgviewer without arguments (and other programs that I tried). The second window is rendered ok when the first window does not have focus, i.e. when another program is on top of it.
I get the same on Windows 7 64 bit with nVidia 196.21 drivers. Not sure what causes this. I tried playing with the "Multi-display performance mode" setting in the nvidia control panel, but no setting made any difference.
I hadn't noticed this because I always start up osgviewer fullscreen on my second monitor only, or in a window. So I'm not sure when that started. It would be interesting to backtrack in the drivers to see when it started, but I don't have time to do that today. It might also be a Windows 7-specific issue, because I remember it working fine on Vista on recent drivers and I just upgraded to 7 a week ago on my work machine.
We also can't immediately rule out some problem with OSG causing this. Even if 2.8.x and 2.2.0 have the same behavior, perhaps it's something we've always been doing wrong but only recently have the drivers become sensitive to it. That's always a possibility.
If anyone else has any feedback (confirmations on their system, or results with other versions of drivers) please post in this thread. Since we're ramping up towards a stable release it would be nice to find out whether this is caused by OSG or drivers or OS.
I can also submit a bug report to nVidia, but I'd prefer doing a bit more exploration on our side first.
Thanks, J-S -- ______________________________________________________ Jean-Sebastien Guay [email protected] http://www.cm-labs.com/ http://whitestar02.webhop.org/ _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
