Hello, I'm new on this forum and this is my first message.
First of all, congratulations for your work I think it is amazing.

the bug that I'm talking is very silly but a little bit annoying it is only that when I'm pressing the spacebar to do a pan it works without problems but if I hold the spacebar to move my pencil/mouse and I attempt to move my canvas the pan tool has changed to a brush tool again.
It only happens on Mac osX I tried windows and linux and works as expected.

for more Info my OS X version is 10.12.6 on Mac Pro 2010 and Mac mini 2014 I use Wacom intuos pro 5.

I hope that can be fix it before the final release

thank you for you atention
