Hello! I have a ScrollViewer on an adt in Texture Mode and on alpha 47 it works just fine. After upgrading to alpha 65, the barColor (which is supposed to be blue) doesn’t show up until I click around in the scroll bar area a few times, and then it appears and seems to work just fine. So, at first glance, it doesn’t even look like a scroll panel!
Here’s a playground ( Scroll Viewer Example | Babylon.js Playground (babylonjs.com)) that shows a really crudely tweaked example from the docs where I take a scroll viewer and put it on an adt in texture mode and then make the child container a lot bigger than the scroll viewer. I can strangely click inside the bar area to make it go downwards, but the bar doesn’t appear initially - and in this case, doesn’t appear at all. In my app, I’m able to eventually get the bar to appear with enough clicking, but I’m hoping there is some overlap between these issues to help get to the bottom of it.
