What happened?

Today I tried again to move my pre-metal version to metal and everything seems to work fine this time. No more rendering artifacts! Cool!
But one thing I noticed is a lot of error messages in my logs

Execution of the command buffer was aborted due to an error during execution. Insufficient Permission (to submit GPU work from background) (00000006:kIOGPUCommandBufferCallbackErrorBackgroundExecutionNotPermitted)

I am wondering if I am just blind and don't see which capability I might be missing. All I do is run my app which is showing a map and sending it to the background by closing it (swiping up from the bottom)

It seems not to affect anything else. It does not crash, but still there are those warnings inside the log, so I wanted to share with you to see if it's something that needs to be taken care of.

Steps to reproduce

Show a map, close the app.
Not happening always, but sometimes. Not sure how to reproduce it on purpose.

Relevant log output
