So I'm loading in a bunch of layers created in ArcMap 10.1 with some pre-defined labels into ArcGIS Pro 1.3. Nothing too fancy. These labels draw almost instantly in ArcMap, but take forever to draw in Pro.
Regardless of how many labels actually need to be re-drawn on the screen, it still takes a long time. I'll zoom to an area in the map with only 2 visible features, and 2 visible labels, and it'll sometimes take up to 15 seconds to redraw the labels.
The draw time varies a lot however, and seems compeltely independant of how many are visible.
What's going on here? The features themselves are almost instant to draw. I've had to remove labels entirely during demos because of the performance problems.
