@troubblegum, thank you for the very clear reproduction steps! I was able to reproduce this issue following your instructions.

After looking into it, this seems complicated, I believe it might be related to how widget geometry is handled by the engine for 3D widgets, where size and position are individual for each 3D widget compared to 2D widgets. I don't see any quick fix and it might require refactoring to handle 3D widgets properly.

For now, please combine multiple 3D widgets under the same widget instance. I'll leave this issue open until I realize a possible fix or community helps solve it
