From 159d3b1b7286d8e037b6637ed107bb811e93f276 Mon Sep 17 00:00:00 2001 From: Ashod Nakashian Date: Thu, 28 Jun 2018 01:02:49 -0400 Subject: sw lok: delay processing idle jobs to let LOK finish initialization When loading document, LOK needs to setup the client view, register callbacks, get document size and type, etc. All of these need to take SolarMutex, which is taken by the idle jobs immediately after loading, blocking LOK from finishing initialization and rendering the first tiles for the user. This gives the user the impression that the document is loading for far longer than it actually is, due to lack of interactivity (or indeed any activity on the screen besides the spinning wheel). By delaying the idle jobs, we allow time for LOK to finish initialization and render the first tiles before the idle jobs kick in and hog SolarMutex.
