Version of ElvUI: 10.79

Did you disable all addons except the two called 'ElvUI' and 'ElvUI Config'?: Yes.

Did you disable all addons to make sure it is not an issue with the WoW client itself?: Yes.

Did you check for lua errors? (/luaerror on): Yes.

If you received an error then post it below (use the 'code' bbcode):
No errors.

Please explain the issue you're having with as much detail as possible. If there is a way to reproduce the issue then mention that too.:
When I click on to a different chat tab, the editbox thing you type into pops up, and I have to hit enter twice to get rid of it, it's quite annoying.

If your issue is graphical then please take some screenshots to illustrate it.

Run through the chat and cvars part of the ElvUI install (skip all other parts). It will reset your chat to default.

I always recommend backing up your WTF folder - where your profiles/settings for all addons, including ElvUI are stored.

Ahhh I'm dumb.. I tried the ElvUI install thing and setup chat a while ago, but skipped the cvars part of the installation. It's fixed now, thanks for the quick reply.
