Qiang, is this covered by your recent Retina-fix?

Qiang, if it helps you out, here are two example videos:

Re#2: I do not think so. As the mouse capture code path is different for tab and screen capture.

Just double clarification that this only happens for our user in tab mode (not desktop).

What is tab mode?

tabCapture

Qiang, can you see if it repros with https://chrome.google.com/webstore/detail/screen-recorder/gdamcnkmddbfhaadidkhahllkabienpk?hl=en-US ?

I think this will likely be specific to an OS + browser combo. Or something specific to this user. Let me know if you would like to setup a debug session with him and I can ask if he's ok with that.

vinay@, that would be great. Can you also try to test if it repros with the app I posted in #8? Since we have the source for that one it makes debugging easier.

Niklase, I would probably not be able to repro since the cursor in my tab recordings look fine on my machine. When I install that app though and click "record a chrome tab", it just flickers. Here's a video:

Also, if one of you guys need to be connected with the user that's affected by this, whose email should I use (and what is it if it's not the public chromium ones I'm seeing here)?

From #1: what I found weird is:
Only the arrow cursor is stretched, when the cursor is a hand shaped, then it looks normal.

Re #8: I cannot reproduce it with screen recorder on my machine.
Re #11: "Record Tab" does not work for you because your chrome version is older than M54.

Re#11: Just replace @chromium.org with @google.com. I could talk to the user, and try to gain more information to diagnose the problem. Can you arrange that? (Possibly next week, as I will be OOO this Thursday and Friday)

Re #13: The user that is experiencing this cursor issue is on M53, so he will likely need something that works on that as well. I've reached out to him asking if he's cool with me connecting you guys. If he is, I'll shoot you guys an email and update you here.

Chrome 54 is rolling out now, so everybody will be updated that version within days. (https://googlechromereleases.blogspot.com/2016/10/stable-channel-update-for-desktop.html)

Windows 10.

According to the user, the OS he uses is Windows 10, and he customized the cursor.

I've verified this issue. 

If you customize your mouse pointer to be a non aero cursor, then it is stretched. I will take a deeper look to see whether we can fix it or not.

Good stuff!
