Blurry Icon - Running websites as standalone "windows"/apps

Hello.

I tried the "install website as app" feature in Microsoft Edge.
It is ok, but when i choose to use a custom icon/png for the web app, the icon becomes blurry. Why is that? And is there fix for this?

Also, are there other methods/programs that can turn websites into apps?

Thanks in advance.

Is the issue present when you use Chrome? How to Make a Website into a Windows 10 App

Yes, it looks good in Chrome. Thanks.
I have sent feedback to Edge-team.
