I found a way its a trick maybe help you too..
just import png small image and put it somewhere outside of the canvas on the game board. Strangely it will make your font looks back in cool ..not sure the internal reason but now if i need to use good quality of fonts i just use any dummy bar or image and put it like this...
try and let me know what you think.
I tried this but am still having the same results.
I made new project, added a text size 24 arial, and the E shows sharp edges/ugly corners.
Added an image outside of he layout, but still the same.
