In the screenshots, notice how the omnibox doesn't show coherent URLs.  They're a mix of multiple URLs from different tabs.

Looks like you are running CrOS M49 build. You have a pending update waiting for restart. Could you restart and see if this problem is reproducible?

I restricted the issue for privacy reasons (screenshots). Looks like one of the file descriptor issues. If you run into this again please file a feedback report and post the id.

I'm battling  issue 611127  after restarting into M50, but I'll try to send a feedback report if it happens again.  How do I find the feedback ID once I file it?

(Note to self: Alt+Shift+I is the shortcut for sending feedback, since the menu item for "Report an issue" won't paint if the bug happens again.)

FWIW, this has been happening to me about once a week for the past month.  I was finally able to capture screenshots to file the bug.

You could just leave a code word in the description. It makes it easier to find. Silly, I know.

Yes it looks like the fd problem we had before. If you're still on 49, please try to let it go to 50 first.

Yes, I'm on M50 now, though it's unusable now because of  issue 611127 .  Still, I'll send feedback if it happens again.

For reference, can you post a link to the bug for the fd problem?

There were several. Like  issue 582143  or  issue 597287 .

Related to  Issue 608024  ?

I just hit this bug again in 50.0.2661.104, shortly after rebooting and restoring a large number of tabs.  I filed a feedback report, which you should be able to find by searching for either "https://crbug.com/611120" or "ihf@".  (It didn't give me an ID to reference.)

Attempting to upload a screenshot from the affected device.

In the screenshot in comment 12, note the following:
1) Right side of tab strip shows a different window's tabs.
2) Address bar is split between two URLs at the same point.
3) Neither half of address bar matches the visible page (chrome://version).
4) Omnibox dropdown is partially visible.
5) Clock is missing.

In this state, menus don't draw.  Machine is unusable once it starts happening.

This is the report, I am taking a look.

I don't have access (anymore?) to the detailed system logs. From what I can see memory is a bit low, but no zram used. But gtt total at 2^32 is fishy.

That was just the total size. I got the logs. There are about 90 tabs/extensions. Heavy use, but should not be out of resources that I can detect.

There is an unrelated crash in the logs.

Yep, judging from the time of that crash report, that was the one that made me restart and restore all my tabs, shortly before the bug occurred (see comment 11).
