When I create brushes to use as stencils the visual stencil overlay does not update. I don't know if this is caused by a setting or bad set-up or if it's a hardware/software conflict. Can anyone help?
1. Create Brush 1 with stencil A
2. Create Brush 2 with stencil B
3. Select Brush 1 and stencil A is displayed
4. Select Brush 2 and stencil A is still displayed but if I paint then stencil B is what is active
5. Switch Brush 2 mapping from Stencil to View Plane and then back to Stencil
6. Brush 2 nows displays stencil B
7. Select Brush 1 and stencil B is displayed but stencil A is active
Screen capture of the above steps 3-7

Hi Charles 
thehomme,
That looks like a (Blender) Bug to me.
I haven't been able to find it in the Bug Reports yet and it still appears to exist in the latest 5.0 Beta, so you should report it. Maybe with a title, something like: Stencil Overlay in Texture Paint not updating.
Ahh ok thanks. The brush UI is pretty disparate and confusing so I wasn't sure if it was something I was doing/not doing or if it was just my computer. Seemed too big and obvious to be a bug. Now reported
