I read through some of the other issues and I seem to have a different issue.
So what I have is a Dragable Panel with a clipping mask on it, and content below it. When it starts up everything is fine, everything is clipped. When you scroll or drag the bar down clipping stops everything shows up, it scrolls, and then clips again. It's almost like clipping gets disabled when you drag or scroll.
Things Already Checked:
1. Everything is 1, 1, 1 scale
2. Renderer is Unlit, Transparent Color
3. Z axis is set appropriately
Any suggestions?
