A couple days ago I had a similar event happen (busy cursor pops up, and a few seconds later normal mouse scrolling occurred). C-h l in that window: [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] C-h l [view-lossage] Just now I had a different event happen -- this time no busy cursor appeared, but the buffer still scrolled a few thousand lines instantly. The selected window was not the window where the scrolling took place. I did C-h l in the selected window and got: [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] [mwheel-scroll] C-h l [view-lossage] Is it possibly the commands with a help-echo prefix? P.S. Is there a way to get the event time in C-h l? If not, I think there should be an option for that.
