But that was to be expected, because it is redrawing more often because of the faster scrolling. Before resizing the average CPU utilization is about 210%, after resizing 280% (on a Core i7). This behavior is reproducible. The difference was more significant in the past, but in the meantime I upgraded to 10.11.3 and made some minor internal optimizations.
