I've also noticed the behaviour of grid.rect() has changed in 2.2.0. Before the fill defaulted to transparent, but now it defaults to white.
The initial value of the 'gp' settings for the ROOT grid viewport has changed in 2.2.0 (see grid/doc/changes.txt). Before it defaulted to transparent, but now it defaults to whatever the 'bg' is for the current device (on some, e.g., png() this is "white", though I'm not sure why right now)
Because many (maybe even most) png viewers do not handle transparency correctly.
