Description: MacOS: Large delay before the red spell checker lines show up after pasting the same content multiple times. Lots of time spend in Scheduler::ProcessTaskScheduling() Steps to Reproduce: 1. Open the attached file 2. Use Instruments Time Profiler (not needed, but shows the ProcessTaskScheduling) 2. Enable the spell checker (ideally to non-english) (it's more the visual impact; not needed for reproducing) 2. CMD+A + CMD +C 3. Hold CMD+V for a while (around 30 pages).. Notice that the LibO keeps processing, when releasing CMD+V (which it didn't do before). And it takes a long time before the spell checker finishes Actual Results: LibO keeps processing 20 seconds after releasing the CMD+V Expected Results: CPU usage should drop within 2 seconds or so Reproducible: Always User Profile Reset: No Additional Info: Version: 6.2.0.0.alpha0+ Build ID: 7cb6dc2652ce7e2e7d9ec7464bb1eed0d93306d7 CPU threads: 4; OS: Mac OS X 10.12.6; UI render: default; TinderBox: MacOSX-x86_64@49-TDF, Branch:master, Time: 2018-08-29_09:02:27 Locale: nl-NL (nl_NL.UTF-8); Calc: threaded

It gets so bad to the point of not even showing the redlining. Reducing the window and redisplaying the window again, cause the red lines to be redrawn.
I have a vague recollection that this behaviour isn't new though...
No repro with Version: 4.3.7.2 Build ID: 8a35821d8636a03b8bf4e15b48f59794652c68ba
