Hello,
I have a couple of issues with this version:
1) Start Black Ink (1920x1080) and zoom right out. Picked any brush and started painting. Then zoomed right in and as the canvas gets closer, the orginal white background is displayed before refreshing the contents
2) I then zoom in and out and it is not smooth but very choppy and I have only painted one stroke.
Did not have these problems in the previous version.
