Performance issues after update Android 11

[EddyLow]

Hi, I've updated my Note 10 plus a month ago and there has been some issues occurring:

1. The swipe down menu is not working smoothly. 

It happens whenever I'm running a game. During the game in full screen, I need to long hold and drag the menu down. Experience before the update, I could just bring down the menu with a touch slide.

2. Overall performance reduced. System is getting laggy, even on performance mode. I used to set the system to power saving mode and it performs even better compared to the current version.

Please advice.
