I just switched over to 4.1 toady and have noticed the GUI text doesn't seem crisp like usual. Shown bellow are screenshots comparing 4.0 to 4.1.
My desktop resolution is 2560x1440.
4.0 - Perfect text scaling, look like any other program
4.1 - Not perfect text scaling, sort of blurred effect from scaling
Both screenshots are taken with the windows Snippet tool and are untouched. They are not exactly the same size because the capture box is hand draw.
