Is the BillboardGui In The Viewport frame?

[UnderMyWheel (Wheely)]

The ViewportFrame is within the BillboardGui as stated in the title and multiple times in the report. ViewportFrames in BillboardGuis are officially supported and have been completely working.

It wasn’t until recently that the backgrounds for ViewportFrames in BillboardGuis are now invisible. However, the rest of the ViewportFrame functions perfectly fine still.

ViewportFrame doesn’t work in Workspace. You can put BillboardGui into PlayerGui and set Adornee to the Part.

It would seem wrong that it appears to partially work then with the border still rendering?
