I just noticed that the latest version of Slack has the same problem, and I didn't notice it before. Since they use Electron, it means that the problem is not tied to my Chrome user profile, but it might be some system setting like screen scaling. I will try to produces a screencast.

In any case, the idea is that you go from top to bottom on column Q only, so that there is a cursor change on every line. When I use a ruler, I have to go farther than to the left of the Q column

I am attaching a recording of a reproduction with the latest version of Slack, which uses Chrome/56.0.2924.87 Electron/1.6.15 (I ran `strings` on the framework file).

I'm moving my finger slowly from the top of the trackpad to the bottom and back, at a constant speed so there is no acceleration factor. I do this once on the blank space and once on the text in the chat window which causes many cursor transitions.

As you can see, the first time I can go to the bottom of the window and the second time only to 3/4.

+reveman@ - would you be able to help triage this?

Thanks for the report. Have you tried this in other browsers, especially Safari? In general, I don't believe that Chrome affects mouse movement. I could be wrong, though, and it's an interesting bug :-).

I wrote a little test program that rapidly switches the cursor. It does seem to move a little bit slower with a similar metric to the one you described: I put the cursor at the top of the screen, then slowly move my finger from the top of the trackpad to the bottom, and check where the cursor ended up on the screen.

I'm not 100% sure that it's real, but if you can reproduce the issue with the attached test program, then you might need to report this to Apple instead.

@sdy wow, I really notice the difference. Perhaps screen scaling is involved, or multi-monitor. I can only travel 50% of the distance while cursyour is active.

So yes, this seems to be an Apple issue. It would be great if you also reported it, Apple looks at aggregate reports generally.

I opened an issue via bugreport.apple.com. This issue can probably be closed…

One last thing! Could you post the Apple bug ID for posterity?
