Hi, by any chance, could someone help me? Before, it didn't appear as a white box surrounding the browser. First, I had to reinstall windows, so everything was deleted, but when I installed opera gx, now I get this box. It's a 64 bit windows 10.

As shown in the picture.

It only appears in opera gx in the other programs including microsoft edge, it does not appear, I would like if someone could help since the truth is that it is very annoying, and more in my view, please help.
