There is an mouse offset of some pixel on the right when the iso 12646 view is enabled.

True, there is an offset to top left, but only for the move handle and only on some pictures. The rotate handle can not be activated with mouseover.
In some older version i noticed the offset for both handles the same.

I have been investigating that and GUI coordinates of cursor seem to have been broken for a long time, only it doesn't show when the image margins are quite small. Increase them by a lot and you get a constant shift for all shapes and color pickers. Workaround for now is to set margins to 0.

1. Good, there is no more offset grabbing the handles off a gradient mask. Rather strange, moving the mask and handles is possible, but when letting go the mouse the mask is jumping somewhere else. This is happening with or without white border.
2. I do not know if intended, but the mouse pointer symbol is switching between a black point in a white circle, a cross (outside the image) and the (normal) mouse arrow.
