Try again, with each of the possible Canvas class:

"
     MorphicCanvas activeSubclass: BitBltCanvas
     MorphicCanvas activeSubclass: HybridCanvas
     MorphicCanvas activeSubclass: VectorCanvas

  self runningWorld ifNotNil: [ :world |
       world invalidateBounds.
       [ world displayWorldSafely ] millisecondsToRun ].
