I just tried both your attached rbxl file and your repro steps on highest quality level and I couldn’t get the same visual bug you have attached in your video. So it appears the issue is fixed.
The current behavior I’m noticing is expected since the glass in viewport frames is in a different environment and won’t get any influence from the main workspace objects.
If you’re still noticing the visual glitch you posted, please re-open with more details that you might have, including any published game and assets that we can further investigate.
