@sdetweil I did a clean wipe on my sd card, and connected raspberry through a HDMI cable. I should have mentioned that this was an issue when i operated on raspberry in headless mode. When connected to desired display with cable everything is fine. But is there any way to fix this so I can work on MM more comfortably from my main PC?

Hi!
I’m working on my own Magic Mirror and im having problem right at the moment of starting the program.
I followed installation guide at https://docs.magicmirror.builders/getting-started/installation.html#manual-installation and when i type npm run start I see extreme screen tearing and graphic “artifacts”

How can i solve this problem?
I have Raspberry Pi 4B 8Gb
