In all Bedrock editions of Minecraft- including Windows 10, Xbox, Mobile, Switch, and so on, so forth- almost all menus and menu movements feature extremely poor framerates. This is especially noticeable with Menu transitions or occasionally scrolling- basically, slide movements of any kind make this issue abudantly clear.

This is clearly not a bug as it has been featured in every single update since the most recent UI scheme was introduced, and this 'bug' continues through beta versions to this day. Whether this is being ignored in favor of the upcoming menu reworks, i'm not certain, but regardless i feel this needs adressing for the primary versions of the game. This level of unpolish and unresponsiveness is unacceptable for the 'primary version' of Minecraft.
