MacOS: App-crash only if two displays are connected

[philipp.hofmann 4]

Hi,

my app runs under Windows perfectly with two displays.
With MacOS and one display everything is fine also.
But my customer sometimes report the following error if they are using two displays:

Zugriffsverletzung bei Adresse 0000000102C2CD7D beim Zugriff auf Adresse 0000000000000000
At address: $0000000102C2CD7D (Fmx.Platform.Mac.TMacMetalView.displayLayer(Macapi.Quartzcore.CALayer) + 173)

Is this a known problem?
