graphic card

[jpartida]

Hello, I updated my iMac 11.2 to Monterey using OCLP, and everything seems fine. However, I have two issues that I can't solve:

1. There is a problem with the graphics card. At certain times, the entire screen gets corrupted with a pattern of conflicts, similar to interference across the entire screen.
2. The Bluetooth Magic Mouse doesn't connect when I start the machine. The window searching for Bluetooth devices appears, but it doesn't find the Magic Mouse until I click it multiple times.

Could you please help me with these issues?
