I can confirm this is happening. As observed here, the Frame which was tweened using the Cubic EasingStyle jumped to (0, 0) and did not tween properly to its final position. It seems to only affect the Cubic, Circular, and Exponential EasingStyles.
The mentioned easing styles which don’t work were added after TweenService, so the impact of this is very minimal. Maybe if the code iterated through all easing styles and used them, it could be problematic, although this doesn’t seem like something that would ever be done. I also don’t believe this is a new bug, this has likely existed since the easing styles were added (in version 395).
Hello. Unfortunately, fixing Size and Position is not on the roadmap as they are being deprecated. As mentioned, it is strongly recommended that TweenService be used instead.
