Paint

• 

  Shape and Texture stamps have no effect with Dodge or Burn Brush Modes. There is no workaround.

• Painting on a newly created layer, which sits on top of another layer that uses multiply blending mode, is sometimes slow.

  Switch to another layer below the newly created layer, then switch back to the newly created layer.

• Transformations on a text layer cannot be undone.
• The text tool (Paint > Text Image ) does not support multi-byte languages such as Japanese, Korean, or Chinese.

Shapes

• Shapes may not work on symmetry geometry.
