Bug description

It can be seen in the video that each tick of the metronome will cause the game to freeze briefly
It seems that the longer the beatmap, the more serious the problem

Taken to the extreme, Hello (BPM) 2022 is extremely laggy

I don't think this problem is related to #20918, in the problem I reported, even only one time point will cause stuttering

[bdach]

@RBQcat then please attach a video of this showing with one time point rather than the tens or hundreds the maps in OP have. preferably also with frame graph enabled (ctrl-f11 twice).

In addition, I found that Caton appears after the waveform image is loaded

I am experiencing the same issue and found out that the main cause is the UI to the right of the metronome (metronome tick delay visualizer?).
Whenever I hover over it and not move my cursor, it stops the updating and the lag is not caused anymore. I recorded a video of it, and I also show how I move my cursor over it like normal. That movement causes a giant lag. I am pretty sure it is the updating of this UI component that makes it all lag.

The metronome causes that UI component to update, which results in the metronome seemingly being the cause, but the cause is probably what the metronome affects.
