Great job guys :slight_smile:
Noticed small thing that if child components have been rotated (via an affine transform), i don’t get same behaviour with d2d renderer vs Software renderer, with d2d component get like ‘cliped’, not sure if there is something special to do maybe…

here quick vid ex of what i mean: i double clic to rotate child red comp, first software, then d2d. can post code in case made mistakes
