Photoshop Legacy PencilBrush stroke not scaling with brush
Hello
I have been having issues since updating photoshop with one brush in particular.
Its the PencilBrush tool - this has been one of my favorite sketching brushes but it has stopped working as it once was. when increasing the size of the brush, it doesnt seem to scale the stroke instead making a scattered line of texture .
Let me be clear, I am not talking about the cursor. I havent got Caps lock on - the cursor scales fine, but the mark just doesnt seem to behave the same way when larger as it does at its default size.
I have also tried updating Wacom drivers and have reset the tools but this didnt help either
You can see in the image below that i have scaled the brush from 9px to 50px but the stroke width is barely any different and the texture is no longer constant.

Any suggestions would be greatly appreciated.
Thanks
