Eyedropper broken on Mac OS Mojave
On the latest version of Mac OS Mojave (10.14.1), Adobe XD's eyedropper tool gets "stuck" and only chooses colors from the actual eyedropper icon itself. It seems to be a graphics issue in connection with Mac OS.
There’s been other reports with Mojave + graphics performance. For those, we have determined they are MacOS based and we’re working closely with Apple Eng to resolve. Can you share the specifics about your system?
