The 60s time is strange, I'm not aware of any mouse-cursor-related timer in blink at that time scale.  Can't repro in Chrome 57.0.2987.59 on ChromeOS.  Maybe something Mac-specific on the browser UI side?

To clarify- the time window isn't a hard upper bound; rather an indication that it usually happens in less than a minute. (sometimes much sooner) Confirmed on a second Mac; could certainly be platform specific. 

Let me know if there is any logging info I can submit that might be helpful.

Tested on Mac os 10.12.2 using chrome M56 #56.0.2924.87 and followed the steps below:

1. Launched chrome and downloaded given html file .
2. Loaded the html page and clicked on "Make fullscreen" button and waited for the cursor to appear for more than 60 seconds and couldn't see cursor.

Attached screencast for reference.

@abought--Could you please check attached screencast and confirm us if we had missed any steps in reproducing the issue and also help us by providing the screencast of the issue , that would help us in reproducing the issue.

Thanks!

Thanks for giving this a check- very impressed by the quick and thoughtful turnaround.

Attached is a sample screencast to demonstrate the problem. In this video, the page goes fullscreen at 1-2 sec, and the mouse pointer reappears at 4-5 seconds without human intervention. Sometimes the mouse reappears quickly, otherwise it takes longer; there doesn't seem to be a set predictable interval.

I also can't reproduce this on a MacBook pro on 10.12 (Sierra) using M56.0.2924.87 -- waited a couple of minutes and the cursor is still hidden. Tried Safari too with no luck.

It's a bit of a long shot but maybe we can see something in tracing. abought@, could you reproduce this while recording a trace? Here's instructions:

https://www.chromium.org/developers/how-tos/trace-event-profiling-tool/recording-tracing-runs

If we can correlate what events are coming in when the cursor reappears we might be able to get a clue but I'm not terribly optimistic.

Is this possibly related to some software you have installed on the Mac? Just wondering if there is anything specific you can try disabling.

abou...@ we are still waiting for some feedback from you. Specifically we are wondering if there is anything special about your setup and whether you can provide a trace.

abou...@ also along the line of your setup. From your screen cast it seems that you have a few extensions installed on your Chrome as well. But you may want to try disabling the extensions and see if you see the same problem or not.

Ping. Unfortunately, if we can't repro and get no other information to go on there's not much we can do and we'll have to close the bug.

Closing due to lack of feedback requested. We've tried different mac devices here and cannot reproduce. We believe it is some additional software installed on your machines.  If the issue reproduces please open a new issue providing the details we requested.
