Not sure if this is related to my setup in some way or a bug… but ive noticed when im in transpose mode and i go to hit a custom hotkey like 1,2,3 etc to switch to a brush i will have to hit the key twice for it to register. Hitting once switches to a default standard brush and hitting the key again switches to my assigned brush for that hot key.
You have to first press Q to change from transpose lines to Draw brushes. And then your hotkey will work perfectly. I have the same issue BTW it´s a bit odd but you will need to get used to it for the moment.
hmm makes sense in a convoluted way… double tapping the hotkey works for now…
