Bartender 3 - Window Server Error in Console

When Bartender 3 is running and I see a lot of Window Server Errors with the message error: [ERROR] - Unknown CGXDisplayDevice: 0x41dc9d00
For some reason Apple added an error log message to a public API call that returns correctly, we have filed a radar bug report to them, but with the new unified logging I don't think they mind the console having tons of messages in it.
You can filter this message when looking in Console, or I believe permanently using the log command line tool / profiles. We will add more info about this soon.
Unified logging is very light weight so you do not really have to worry about this (hence why Apple have left so much logging in).

NOTE: As of macOS 10.13.4 Beta 1 (17E139j) Apple appear to have fixed this Error message, so it is no longer showing. Hopefully with the proper release of 10.13.4 the message will stop.
