问题
Something has changed in the way the Forge Viewer is displaying our selected objects. First when we selected a window it would stay transparent, and was only highlighted with the default or given color. Right now the windows are rendered non-transparent with the default or given color:
This only happens at the first selection, the first selected object will stay non-transparent until you pan/zoom the scene or Zoom in (F) on another object:
I already tried on every selection:
viewer.impl.invalidate(true);
This will reset the pre-selected object to his original transparent material, but the selected object will be highlighted un-transparent every time.
I do not use a custom selection here, this is just default behaviour. Any advice?

This issue was fixed in the Viewer version 6.4 Currently we are at version 7 let me know if the problem persists but should be good to go now.
