I am using RMBP, and I can feel obvious lag when using Go to Anything feature, really annoying. I tried another macbook with lots of worse configuration but still better than feeling on RMBP.
Then I tried to drag the ST2 window from Retina display to the second external display, which is not retina. And everything changed, the performance is lots of better on the external screen. I tried both 2219 nightly and 2210 dev, tried enable or disable gpu_window_buffer, same behaviour.
Something must be done for retina display, otherwise it's really annoying, one of the best expericen on ST2 is the fluent, right?
