Just updated to 2019.2 and noticed the font change, can't mis it: it's hideous and barely readable.
How to fix?
Only other posts about this version and the font change is not for PHPStorm and/or Windows (10).
I have no idea how to give you information about the instance I am running, so if you request any information, please provide me with the necessary information to deliver that.
Also, I hoped the CPU hogging issues would be resolved with this version, but my hopes are not to be realized...
