I can't see were you had your mouse pointer while scrolling fast. But this is exactly the right click menu I was talking about.

I just enabled crash reporting and generated a report with this id: d26b7951d7fef35b

I'll try a few things to see if it changes the behavior and report back.

Thank you for providing more feedback. Adding the requester to the cc list.

As I mentioned before I'm running Ubuntu 17.10, and I just noticed that the crash is not reproducible if I run chrome/chromium in a Xorg session. Within a Wayland session it happens every time: https://itsfoss.com/switch-xorg-wayland/

Maybe this already helps to pinpoint the cause?

Thanks for the update!!

@andi: Could you please update your Chrome to the latest version #65.0.3325.146 and check if you still face the issue? If so attach a one more Crash I'd from chrome://crashes?

Thanks!!

Nice, it looks like the update fixed it

> Chrome: Version 65.0.3325.146 (Official Build) (64-bit)
I'm not able to reproduce the crash in this Chrome version

> Chromium: Version 64.0.3282.167 (Official Build) Built on Ubuntu , running on Ubuntu 17.10 (64-bit)
Looks like the chromium build in the repo is not updated yet, and I still can reproduce the crash here.
