Text input field loses focus while typing

[marius-dr]

Kibana version: 6.1.3, 6.2.0

Browser version: MS Edge 41.16299

Original install method (e.g. download page, yum, from source, etc.): BC Build

Description of the problem including expected versus actual behavior:
When I try to enter any text in an text input box, the box loses focus any time the vertical line goes on and off and this leads to lost characters. On a normal typing rate, every 3rd character gets dropped, looks to be something to do with type-ahead.

In the gif below I was trying to type the alphabet and you can see how many letters were dropped:

Lee also encountered something similar.

I saw this problem really bad on 6.2.0 BC1 on Chrome, IE 11, and Edge browsers.

And I don't see it at all on 5.6.7 BC1 on Chrome, IE 11, and Edge browsers.

These are similar issues;
#14628
#14909

@LeeDr, I suspect this is specific to the index page because #14909 was supposed to be fixed with #15479. If you can repro on the visualization or dashboard search listing pages, let me know and I will look into it. Otherwise I'm going to tag as a management issue.

Is this Chrome on Windows or OSX/Linux? Or all?

Does this reproduce on master?

[marius-dr]

Reproduced the issue on the 6.x branch today and it blocks running Selenium tests on IE.
Will update with status on master as well.

LE:
Master seems fine for me when running from source, I'll keep trying, but it seems that it might be related to the number of indices on the cluster.

[chrisronline]

I tried this on master and didn't see an issue. It might be related to less than great hardware running Kibana. Is it possible to test that variable?

[timroes]

Could you please validate if that's still an issue. I think there were a couple of issues also around EUI elements, so I think that might have been fixed?

this seems to have been fixed, if encountered again please reopen
