Further fix, and recommendation:

With current settings, Galculator creates an unsightly additive (intensity increases while mouse remains over panel) thumbnail artefact, which remains after thumbnail preview closes (screen capture link below).

There's two ways to fix this.

# Method 1:
org.compiz.profiles.mate.plugins.decor

- active-shadow-x-offset 6
- active-shadow-y-offset 6
- inactive-shadow-x-offset 6
- inactive-shadow-y-offset 6

+ active-shadow-x-offset 2
+ active-shadow-y-offset 2
+ inactive-shadow-x-offset 2
+ inactive-shadow-y-offset 2

# This method benefits all Compiz windows as shadows become more proportionally balanced, while previous setting creates a larger offset shadows (with seemingly no shadow visible top + left).
