Question:

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:

<img alt="Attachment 1" class="b-lazy" data-src="https://i.stack.imgur.com/NSE15.jpg" data-original="https://i.stack.imgur.com/NSE15.jpg" src="https://etrip.eimg.top/images/2019/05/07/timg.gif" />

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:

<img alt="Attachment 2" class="b-lazy" data-src="https://i.stack.imgur.com/heNq1.jpg" data-original="https://i.stack.imgur.com/heNq1.jpg" src="https://etrip.eimg.top/images/2019/05/07/timg.gif" />

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?

Sorry about this issue, ee still investigating this (since @JaimeRosales first reply). Our tracking code is LMV-3722.
