I guess an extension will work too.

@sgunhouse Sorry my post was misleading, yes, I can also read characters and characters are not "blurred" which can't be read.
However, like following screenshot(please comparing above part, which background-color is black, and below part, which background-color is white) characters are little blurred. It doesn't matter to read but looks not clear sharply, in one word, it's ugly.

So this is a little problem(not bug) and I've posted on [Feature Request] category, it's not so bad if this problem remains but it's better if improved.

@BillGee2810 There are third-party apps that do this.

I use FastStone Capture ($19.99 Shareware for Windows), but there are other free apps and/or extensions.

@Pesala There is no need to take this extra step.
I know this is the way to go at the moment, but wouldn't it be better if you could just quit?

A good string from Vivaldi Translation project that resumes my felling:

"Reduce your use of third party apps, thanks to everything already built in."
