Weight painting only visible if Subdivision surface modifier is assigned.

Hi.
My problem is in Blender 2.73a (not previous versions)… Only gradients and colors of weight painting get visible if a Subdivision modifier is assigned and View value in this modifier is upper than 0.
The same happens with vertex paint…
Maybe a bug?

I have Linux Mint 17 - 32bits -

Hi. I have the same problem (ubuntu 14.04). Did you already solve it? I just use to turn on subdivision modifier in ‘simple’ mode.
