I was going through list (the first post)...
I changed some of the settings and some other things in the system menu, but somewhere for some reason, the font of most applications changed, and now they seem thinner and don't seem to render correctly:
I went through what I think was all the options I changed and can't seem to bring back the correct/better rendering.
I didn't change anything in the font management.
application appearance > style > Fine tuning I now have it set to high resolution high cpu, but it doesn't help.
dektop effects > All effects menu, there doesn't seem to be anything related.
Workspace appearance is untouched.
I'm not sure what could it be.
