so then ran

npm run start:wayland

and I get:

I then did:

pm2 stop 0

pm2 stop 0
pm2 logs --err

and I got the following:

Is this just okay to leave as is? If I hadn’t been checking for other errors, I wouldn’t have known this was popping up as my screen is displaying as expected.

Hope this makes sense.

I’m pre-empting you asking about that log, here is the last one:

But at least my screen is populating fine :)

If the os has it enable in boot/config.txt
Then you can try

export ELECTRON_ENABLE_GPU=1
Then
npm start

If that works you can update the script used by pm2
