The bug reported here was already fixed some weeks ago, but there were more issues. Modifier display in face select and paint modes was never properly finished. This fixes some small drawing update glitches, and only allows modifiers that preserve a mapping to the original mesh to be applied. Otherwise selection and painting isn't even possible.
