Hi Christoph.

I would not want to do that for every morph. That's the wrong place to fix it. Just take a look at HandMorph and fix the creation of that cached picture.

Hi Marcel!

Would this be a too simple fix for the issue?

In Morph >> #fullDrawOn:
      ...
  "Pass 1: Draw eventual drop-shadow"
-     self hasDropShadow
+ (self hasDropShadow and: [(self ownerSatisfying: #isHandMorph) isNil])
+ ifTrue: [self drawDropShadowOn: aCanvas].

      ....

Best,
Christoph

We already do at some places. See (some) senders of #hasDropShadow:. Still, it feels like a workaround and does not yet apply to the hand's caching procedure. See HandMorph >> #updateCacheCanvas:.

Hi all,

I wonder whether we should turn off drop shadows during grabbing a morph?


And it looks even more strange when grabbing menu items (citing from Squeak by Example):


This is related to the #menuAppearance3d preference, but I never met a physics system were shadows can throw their own shadows 🤔


Best,
Christoph
