Previously the beatmap would begin loading at the same time the
`PlayerLoader` class was. This can cause a horribly visible series of
stutters, especially when a storyboard is involved.
Obviously we should be aiming to reduce the stutters via changes to the
beatmap load process (such as incremental storyboard loading,
`DrawableHitObject` pooling, etc.) but this improves user experience
tenfold in the mean time.
It was reported that mods selected in song select would show up during
loading of replays which were recorded under a different set of mods.
This was caused by BeatmapMetadataDisplay accepting a plain read-only
value of the Mods bindable in PlayerLoader.load(), therefore making the
mod value assignment in ReplayPlayerLoader.OnEntering() have no effect
on that component.
To resolve this issue, make BeatmapMetadataDisplay accept the
higher-level bindable, bind to it locally and pass it down the hierarchy
to ModDisplay.
This took around under a hour to implement, it has the same behavior and content from osu!stable.
A notification will show up when the user has either its master or track volume set to the minimum, clicking it will set it to the default values.
