A while ago all the GTK software were looking awful under KDE but that was not problem because the only one I use all the time Chrome. It was looking good but all of the sudenly it looks awful. I tried
this as a way to integrate KDE and GTK but it didn't work at all. Actually, it was what borked stuff in the first place, even removing the files and going back to what it was before Chrome still looks awful. I tried a new user and even with a new user Chrome looks bad.
