Recently experienced the mixer panel on the screen of my Mac Book Pro going blank while mixing.
Music kept playing but lost all control.
Also in the same session music would glitch.
Shut down Traktor software and hardware and restarted and the problem didn't occur again.
Using Traktor S4 + Mac Book Pro 2015 Catalina 16mb - been reliable as for ages.
Clean machine using only 15% of hard drive.
Chrome was open and Apple Music but nothing else.
Have the latest Pro 3 update.
Have a big gig coming up and wish to know possibly fixes?
Is it worth a reinstall or would it be the laptop.
Ideas much appreciated.
