Hi Harry,
The bug 4399760 -
Multiple views config. might not show all visible objects in every view
mention is already fixed in the upcoming v1.2.1 release. It also
fix 4421284 which may cause geometry in whole scenegraph lost.
Since texture works fine in v1.2.1 beta2, it is recommend you
can switch to v1.2.1 once it release.
Thanks.
- Kelvin
