I have been trying to fix this for a while and now it is getting really annoying. All my text and anything that I fill is jagged. The image below I filled with the polygonal lasso tool and it looks very jagged.
I have the DPI on 300 and have tried going lower and higher but it doesn't effect anything. I have tried a lot of different ways to fix it over the year but nothing seems to work. It used to get worse every time I resized the image, but I ended up finding a fix for that.
I am not sure if this is just a me problem since I have a weird resolution 1400x900. But completely straight lines are jagged and it is very frustrating. Any help would be appreciated, thank you.
