• i have 2GB RAM (and also on computer with 4GB RAM) and model is rendered, everything is ok
• then click in external app (or different tab in browser) and return back, model hides, but click on canvas, model is again visible
• in what is problem? RAM?
• how is minimal system requirements for view model?

Probably the problem is with Z-index. A workaround can be to call model.viewfit when entering and leaving the box, this would refresh the layout. However, I believe there should be better fix for this.
