Currently the icon used for Emps-World is a bit blurry on desktop, but the png file in emps-world's cache is sharp.
I thought the problem would be because of the file being a .png file not an .ico and that's exactly what the problem is in my opinion.
I created a shortcut of Emps client and used a converted .ico file and the outcome was a perfectly sharp icon. So, why not use the .ico file instead of the .png one?
