I use the Surface Pro 3 to draw here and the tablet mode does not seem to get detected but that's fine. Though, There's a horrible lag when i make a stroke for 1-2 seconds. I disabled flicking and press and hold function cause thouse would lag on a wacom. On other flock sites like skycows, the lag is not there at all. I hope this get solved soon. I als tried this on a Huion GT-190 Pen display monitor and it lags too directly connected to my Laptop with i7.
