Steps to reproduce the problem:
I have a curious bug but this is messing me up a lot. When I type in some sites, but also in Gmail and Google Inbox, the accent has a very strange flaw. I have to press the accent key three times for it to work. Here's an example:
eeeéééé
eeeééééééééé
oooóóóó
oooó
That is, only after I try to accent a letter 3 times (like the letter "e") does the accent actually work.
I tried to change the system language to English and then go back to Portuguese, but it did not work.
Accentuation works normally in Google Docs, for example. I mean, the physical keyboard is working normally. But I bought the Chromebook especially for answering emails, so I'm having a problem.

What is the expected behavior?

What went wrong?
I think I figured out where the mistake was. The spell checker was on the aggressive mode and I deactivated it. Now the accent is correct. So it's a spell checker bug. Too bad, the spell checker is very useful, but it was disturbing me

Did this work before? N/A
