Hi I am using Photoshop about 6 years and I never faced this problem. When I type in Photoshop, the fonts are not looking smooth or sharpe. the edge are blurry and zigzag. Not only fonts but also the smart objects, like import from illustrator.
I have searched for solution, everybody talking about Anti-Alise (Sharpe, Strong, Crisp, smooth etc.). But is not matter of that. The whole photoshop canvas looks blury I think.
There is no problem with mine Adobe XD or Illustrator. Only photoshop. even I have tried old version of Photoshop CS6. Same issue.
You are zoomed in to 400% so each image pixel is being shown using 16 screen pixels. At that magnification you are seeing the anti-aliasing which is used to prevent slightly sloping edges looking jagged
But are you sure? I faced this problem just last 2 days. If zoom is the issue than how possible to work. I mean what we are seeing on Monitor those are visual. What about a small business card? It is only 3.5 inch but we have to fit it to whole canvas like 600-800% zoom even more. Of course you will not work on 3.5 inch (100%) display.
I am not zooming much as a single pixel/dot. I am working on photoshop about 6 yers and I have idea about magnifing.
How I can explain! I am not elarging the size of any object I am trying to magnifing.
Do you think it might cause of another isuue or my Photoshop software damaged?
