That was my experience, other than I got impatient enough the first time by trying to move browser windows around and such while the process was under duress, that it felt pretty hopeless. I'm sure it would have shaken itself out eventually, but since the browser process was pegging a CPU core and I turned off my power saving features....well my laptop with heat dissipation issues overheated and it did a safety shutdown on itself.
After it cooled off a few minutes and I returned to repeat the procedure with my CPU performance turned down a bit and keeping my hands off the window adjustments....it eventually did catch up as expected.
P.S. I love the use of splort...☺
