When I turn on preference showDebugDamage there are some issues when dropping tiles in the ScriptEditor. A rectangle in the top left corner flashes, and a large part of the screen is redrawn when the tile is dropped, from top left of screen to bottom right of ScriptEditor. I guess this will slow the tile scripting responsiveness. Also the Viewer flap tabs are redrawn quite often, not flap tabs for SketchMorphs, but for other morphs. Karl

Thanks Karl for reporting! We did use showDebugDamage when damage rectangle merging was too eagar^^; But after that we didn't look at other places with the option turn on yet.

I did some bug hunting on the ScriptEditorMorph redraw bug and it is really hard to track down, at least for me :-) It seems the bug is related to a bug in Squeak3.9 when SystemBrowsers causes extensive redrawing when the comment pane pops up and hides. I have looked at Morph>>privateAddMorph:atIndex: and a few layout related methods but have not found the cause yet.

I think I fixed it. Seems like the morph being dropped needed a specific position to be dropped otherwise it would be added to the top left corner of the screen causing lots of screen damage. karl
