So we've always got the basic scenario to fall back on where there is just a single view and things are essentially identical to a standard non-CompositeViewer setup.<ref>https://sourceforge.net/p/flightgear/mailman/message/37076818/</ref>

=== Potential Issues ===
So far, it seemed we 'Cant Use' CompositeViewer because of $reasons in the Effects code<ref>https://sourceforge.net/p/flightgear/mailman/message/26189393/</ref>. Maybe the reason is simply that it needs some work to move away from the single CameraGroup, however.<ref>https://sourceforge.net/p/flightgear/mailman/message/37059939/</ref>
Also, a number of senior contributors have previously pointed out how our existing tile manager/paging infrastructure may not yet be in shape for a CompositeViewer port, poweroftwo's osgEarth port however is using OSG's PagedLOD exclusively, and osgEarth itself is known to support CompositeViewer<ref>https://github.com/gwaldron/osgearth/issues/1300#issuecomment-565734550</ref>, too: https://gitlab.com/poweroftwo 
So, to troubleshoot this further, it'd make sense to exclude the usual suspects one by one:
* disable multi-threading (see Torsten's comments about known issues about multi-screen/multi-GPU setups at [[Howto:Activate multi core and multi GPU support]])
* disable scenery/terrain
* use [[Draw masks]]
* disable effects
At that point, we should be able to nail down where the culprit is, i.e. what needs changing.
Jules shared the patches (topic branch, see above) so that more people can get involved in testing and making progress.<ref>https://sourceforge.net/p/flightgear/mailman/message/37058676/</ref>
