manjaro linux, ati radeon 4650 (radeon driver)
Broken: (example: 2.70 19e627c , see splash screen)
Short description of error
Blender doesnt draw the vertex paint at all when using a mouse.
shift+k (fill color) works, but the brush painting doesnt.
With the Draw Brush.
If you select specific faces in edit mode and toggle on face selection mask in vertex paint mode, shift+K doesnt work at all. I wish it could fill only the masked area.
Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
