A number of my users are reporting crashes of my app on macOS Sierra 10.12 (16A323).
All crashes seem to be caused by a call to “retain” on [_NSCGSWindowBuffer colorSpace].
Did anybody else run into this? This seems to be a specific problem on macOS Sierra. I've not recieved any crash reports like these for previous versions.
Full stack trace below:
