Sometimes I can't scroll down normally

What I’m trying to do

I uploaded the video of my problem.
Sometimes, I cannot scroll down to the bottom of the Explorer.

Things I have tried

Zooming in and out doesn’t work.
Updating Obsidian doesn’t work.
Turning off using the community plug-in doesn’t work.
Stopping using the CCS snippet doesn’t work.
Reopening Obsidian doesn’t work.
Restarting Mac doesn’t work.
(I am using Mac Air M1)

However, sometimes this problem is solved without any clue.
I don’t know the reason or any trigger.

Is there anyone who is experiencing the same problem as me?
or is there anybody who can help?

Thank you in advance…
