From 1062580959edcb03cce8419e8c16dea5fa69effa Mon Sep 17 00:00:00 2001 From: Olli Parviainen Date: Sat, 8 Dec 2018 16:37:04 +0200 Subject: Accelerate the break-apart operation for larger paths by disabling redrawing the canvas during the break-apart algorithm is running. Testing this change with a large pathset accelerated the break-apart operation duration from 24 seconds down to mere 4 seconds.
