This is the new code I use to create my multi sampled windows:
ref_ptr< DisplaySettings > displaySettings = new DisplaySettings;
displaySettings->setNumMultiSamples(16);
modelView->setDisplaySettings( displaySettings.get() );
modelView->setUpViewInWindow...
I can now mix multisampled and unmultisampled windows in a composite viewer.
Thank you!
