Tracking widget does not obey display color management
Bug - Tracking widget does not show display colour management
Set working space to ACES (linear colour space).
In the "View" menu turn on "Use display color management" to view the non-linear image.
When you use the tracking tool and adjust the point tracker's widget, the image inside the widget is still displayed linear (= very dark) despite the set display color management. Setting a tracker point is very difficult.
