Any idea?

MacBook Pro (Retina, 15-inch, Mid 2015) / High Sierra / ASUS MB16AC
Hi,

This is a known operating system bug in High Sierra. We have investigated it and we don't think there is anything we can do about this issue apart from reporting it to Apple.

To raise the priority of this issue with Apple we suggest to open a bug with them on bugreporter.apple.com. If you don't have a developer account, then the normal support page offers other options: https://support.apple.com/macos

You may want to refer to our own bug on the topic (ID 33650324) and/or Apple's internal one (ID 26394372).

Best regards,
Carlo
