I just updated from Xubuntu 16.04 to 18.04 and it seems that someone played with the Numix theme making it more ugly.
1.The panel font color "white" is not "white" anymore, is some kind of "grey".
2.The "System load monitor" has a white background, instead of black one, like in 16.04, now it looks really horrible.
3.The start menu was dark, now it's a light grey.
4.The text for a a selected tab is red, instead of old normal black.
I have tried Oomox but I did more good than bad, therefore is there a method to just copy the entire theme from 16.04? Also, where can I put some bugs related to this, especially for the horrible white background of "Load Monitor"?
