How to reproduce?

  1. Run the test script "plotpy\tests\widgets\test_simple_window.py"
  2. Add a random image
  3. Show the contrast panel (right-click on the canvas, see context menu)
  4. Select the image item in the canvas: the levels histogram is plotted in the contrast panel
  5. Open the "plotpy\tests\data\brain.png" test image
  6. Select the image: the levels histogram is polluted with the one of the previous image
  7. Remove the images: the levels histogram stays, no matter what is done afterwards
