I am currently developing an UWP application where the user draws some shape freely using the InkCanvas element. At some point I need to flip the whole canvas 180 degrees as if showing the backside of a card.
To my surprise, applying a PlaneTransform with positive RotationY to the InkCanvas makes the ink just drawn by the user disappear, and all further input is disabled. I can understand disabling the input when the control is undergoing some weird perspective transform. However, I was surprised to find that it also stops drawing the already existing strokes.
As soon as the PlaneTransform's RotationY property returns to zero, the existing strokes come back and input starts working again.
Is this a known issue? Do I need to convert the strokes in the InkCanvas to a fixed UIElement before applying a projection effect on the drawn shape?
