Recently, a black outline started appearing on my viewportframes when this previously wasn’t the case
I have an updated & an old version of studio running at the same time (Haven’t restarted the older version yet) so here is an image of the before & the after:

Expected behavior

I’m assuming something got updated and that this is an unintended side-effect, I don’t expect there to be a black outline showing up

The RBXM file is posted below, I used the same model in both the already-running studio and a recently-updated studio

My game is affected by this on a whole other level.

This is what it used to look like before:

Roblox needs to fix this bug asap.

Is the Viewport Frame that tiny gun graphic in the right-hand corner

We’ve rolled back the flag change that caused this bug. Can you confirm if it still reproduces for you?

Seems to work normally on my end.
Now the ViewportFrame's BackgroundColor3 tints transparent parts and determines the thin outline color as opposed to the black tinting and outline caused by the recent change.

Thank you for working on a fix for the old BackgroundColor3 bug. While the bug can be partly mitigated, it’s still annoying especially due to the colored outline. I assume though it doesn’t really have an easy fix.

Glad to hear its working again, sorry for the trouble with this

I do think the original background color bug is fixable.
