Minor issues

For new animation container, filter does not work in 3.49. When I choose colorize or Grayscale, works correctly in editor, but not on wallpaper.

When I use squircle as a mask, does not work as developer intended. It acts as an arc...really weird.

When using stack group with an element inside it marked "remove", it adds a small space. This throws size of stack group off. Example...create a stack group with 4 elements in it and another stack with 5, but set layer to remove on one of the elements within it. Both stack groups should be same size visually on wallpaper, but it is not. The stack 5 will be slightly longer because the hidden element adds a little space, like 2 points.
