Sorry if the thread name isnt really clear, and i pointed the newest version but i noticed it on the r109 too.
The issue is that sometimes, the object using the platform behavior after landing, it will go a pixel inside the solids.
Heres some screenshots, one from my own project i started a few hours ago

And two from a game from the arcade which i forgot the name now (sorry <img src="smileys/smiley9.gif" border="0" align="middle" />)

On the first image you can see his little feet is perfectly aligned with the grass pixels, but on the second one it goes a pixel down into the grass.

Yeah it's been like that for a while..A quick workaround is to set your player's Y to the platform's Y whenever you land while overlapping one (provided your platforms' hotspots are at the top.) Only problem is you can see the player being pushed up a pixel a two every time you land if you look closely, but it's better than nothing.
Oh that works, theres a very small flicker but i guess it wont be an issue. Its better than seeing the sprite inside the ground, and it gets really worse when the pixels are at 3x :|
Anyway, thanks for the quick reply :D
I've taken a look at this and done some work refactoring the Platform behavior to be more pixel perfect at small scales like this. So hopefully the next build will resolve it.
