My Macbook Pro 15" Retina, Mid 2015 - Graphic glitches when I overexert my computer

Hate to tell you this but you should have checked on this and other Logic boards before "upgrading" to Catalina which is truly a dog. Logic and Catalina don't play well together on some systems. You will have to wait for a Logic and-or Catalina fix.

There are a couple of things to try. If you have the Macbook with graphics switching.

How to Disable Graphics Card Switching on MacBook Pro

1. Go to the  Apple menu and choose “System Preferences” and then go to “Energy” control panel.
2. Uncheck the box next to “Automatic graphics switching”

The other thing you can do is try running Logic in non-retina mode. Open the Applications folder, right-click on the app you want to open in low resolution mode and click on  Get Info from the list. You should see a checkbox for "Open in Low Resolution"

See if that helps.

Josh hi

I just remembered I met a guy last week who updated his 2015 MBPro to Catalina, he had problems and downgraded back to Mojave, not sure how he done it but he said it took a while, so it can be done, maybe there are some videos on You Tube.

Hi Josh

Unfortunately this sounds like another Catalina issue, especially since you say it started since you updated your OS.

Seems like this happens with some computers, though I know people who have upgraded to Catalina with Logic and have no problems, though they all have iMacs, not sure if that makes any difference.

Whilst waiting for a fix I would try out Pancenter suggests.

It is a nightmare that has been reported many times on here, so are not the only one, not that that helps much!

Good luck
