Going to the viewport and clicking anything and going back to the texture paint window causes it to not be undoable, skips latest strokes.

Exact steps for others to reproduce the error

Germano Cavalcante (mano-wii) triaged this task as Confirmed, High priority.

I'm not sure but it should be related to the same problem on T61263

Also here are steps to reproduce the behavior:

  1. New File, open Image Editor and 3D Viewport side by side, create an image, attach it to Base Color on the default cube.
  2. Edit cube (to put 'Toggle Editmode' on undo stack)
  3. Paint mode, Paint a stroke on image
    • at this point the undo history from top down is ['Image Paint', 'Toggle Editmode', ...]
  4. Undo
    • notice the stroke is still visible
    • history is ['Image Paint', 'Toggle Editmode', ...] with the dot on 'Toggle Editmode' instead of 'Image Paint'.

Tested on Blender master a6b7ee2 (2019-07-17)

Agreed -- I had the same problem
