I can reproduce this lag with Kate itself, so reassigning there. I'll also have
a look at that now.

Perf already shows that some excessive repainting is obviously at fault here:

Git commit 8c6a18964e0c0684d5ec068e686ed41aeb0fd657 by Milian Wolff.
Committed on 30/01/2016 at 16:03.
Pushed by mwolff into branch 'master'.

Only update the palette once for the change event belonging to qApp.

This fixes the massive freeze that occurs when the global color
palette is changed. Note that the qApp event filter includes change
events to many objects, but we only want to update once.
