Unable to reproduce the issue using #59.0.3071.115 on Linux Ubuntu 14.04. Able to add the extension without any freezing as per the steps mentioned in original comment.

Requesting MTV team for further triaging of the issue as we don't have Debian buster/sid OS with us.

I checked the same behavior with the same google-chrome version on another laptop, which did not exhibit the problem. The laptop where the problem occurs is a Dell XPS 13 9350, with a Skylake processor/GPU (i7-6500U). I also checked chromium on Debian, version 59.0.3071.104, and the problem does not occur.

I attempted removing all chrome data and purging the package, but the problem persisted. I also tried attaching gdb to get a backtrace, however, I'm not sure where to get the debug symbols.

Lastly, the problem is resolved in google-chrome-unstable -- 61.0.3159.5-1. I hope this helps and let me know if there is more information I can provide or where to get the debug symbols for the package.

I continued to use chromium and google-chrome-unstable today, but both eventually exhibited the same hang behavior, although it's harder to reproduce the issue. In the case of chromium, the hang appeared when a pop-up was supposed to be drawn while removing a gist from github.com (go to gist.github.com). Chrome exhibited the hang when drawing the "spinner" icon for a page.

I can't tell if it's the same issue and it is harder to reproduce. I'll attempt to build chromium from source this weekend and attempt to get a backtrace if I can trigger the same behavior.

I can reproduce this bug with the chromium build on Skylake by creating and then attempting to delete a gist on github.com (https://gist.github.com). Debian chromium version is: Chromium 59.0.3071.104 built on Debian 9.0. I'll look into testing the behavior from master this weekend.

I haven't been able to reproduce this.  Did you have a chance to try testing from master?  (Or has anyone else seen this problem?)

Just finished building chrome from master and can't seem to reproduce this issue. I did notice that the modal rendering has changed for the extension pop-up and same with the github gist. I'm going to close this issue -- will report back if the problem reappears.

Thank you for providing more feedback. Adding requester "rdevlin.cronin@chromium.org" to the cc list and removing "Needs-Feedback" label.

Actually, I can't figure out how to close it. Someone who can, please close this issue :)

Thanks for your investigation, timur@, and glad the problem seems to be resolved!

I've bumped into this again. Running with the build of Chrome from August 5th, I tried launching the browser with "--single-process --no-sandbox --no-gpu" with gdb. I attached the output from "thread apply all bt" when the browser hung. I also have the core dump, but it's 2.2GB. If it's useful, I can upload it somewhere and provide a link.
