Hi @Vikram200526 and @joelbloxx, thanks for your feedback!
Currently this is working as designed, in landscape mode the safe area insets are applied symmetrically. Here is the announcement post for more info.
This was a design decision made for this feature, but we understand that it might not always be the right choice for all games.
I will investigate if we can add something like ScreenGui.AsymmetricalLandscapeSafeInsets: boolean to turn off the symmetrical insets.
