I tried out 14.1 with the custom JDK for Mac OS and the fonts are looking better than they do with the non-custom JDK. However, there are now very noticeable black artifcats around each letter. I tried to zoom in and get a good screenshot of it but couldn't figure out how to get a screenshot when zoomed in. So I have included a non-zoomed screenshot and it is still pretty noticeable. You can clearly see the black artifcats around each letter.
I know Jetbrains is actively working on this font problem in the Mac OS JDK (hence the custom JDK). Just providing my feedback.
