Visual Bug on Brave

If I click anywhere in any page, a “typing bar” appears, like the bar who appears when you are typing something, that shows and hide, shows and hide.

In this video I’m showing the problem:


Everywhere I click, the bar appears.

Brave Version( check About Brave):
Versão 1.18.78 Chromium: 87.0.4280.141

Additional Information:
I’ve tested more than one version, but the bug continues appearing

Ehh…
Can someone help me?
