I just updated to Fedora 30 and it seems to already come with 3.32. Overall i’m happy with the new Adwaita theme. I’m not sure if the transparent top bar is gone, or if that’s a bug. Other than that, i’ll finally stay with the stock theme for the first time since i switched to linux probably.
I’m not a big fan of the new older Icons, but all the other icons look really great. Now all the Apps need some Updates. Evolution for example seems to completely rely on older icons.
Overall, i’m really happy with the redesign. No comment on Performance yet, as i have to test some more.
