I'm attaching another video which shows the delayed cursor issue.

The mouse cursor keeps moving even after I get my finger off of the touch-pad.

I confirms this is still happening on the latest canary.

Google Chrome	66.0.3350.3 (Official Build) canary (64-bit)
Platform	10424.0.0 (Official Build) canary-channel eve

Yes, this is different issue than original one. 

I don't think this is P1 as this requires me to continuously moving the cursor on notifications for several seconds though. I have some idea and I'll look into this when I have time.

JFYI: "original issue" mentioned in the comment #3 was Issue 798056.

Use the cursor stored in Widget for regular surface as well.

The original CL crrev.com/c/903223 changed the GetCurosr logic
only for notification surface. Regular exo surface should do the same.

This also removes obsolete path.

https://chromium-review.googlesource.com/c/chromium/src/+/903223 was backported to M65 too, does this need M65 backport too?

not sure if this is critical, but adding 65 as well.

It looks pretty horrible and extremely easy to trigger.
Do you feel the fix is too risky? Ideally we should give user a PE experience.

+josafat,bhthompson for M65

Lets see how this does in 66 before merging to 65, we  can probably still catch a second stable here. 

I'm still waiting for approval to merge to 66, in case it's not obvious.
