the text blurry is only in edge canary, in old edge and chrome firefox opera, all are fine. the browser window blinks and the text becomes blurred
What version is this? Seems like some old, I even didn't found something similar? But if only this one background image looks blurry, then maybe it is already made so. Take image url and open it in new window. Personally, I don't see anything strange here. However, I do not have a link to this image so I cannot view the original. Please provide the original link.
I see. I have never used Chrome or old Edge as I was a Firefox user since 2006 or something until new Edge released.
On Firefox it is not available, but the drop-down menu is there also available. In fact, it's also available in Firefox, but not by drag-and-drop, but slightly different.
Murphy's law If something must go to ass, give it to Microsoft and it is done. It's hard to imagine how they can do so well, but everything they do, ends at that place. Chromium based Edge is the next good example.
Who stepped on your wart? And at all, it is not your business, what am I doing better or worse? Try to cope with yourself.
