... is a major step down from Gnome 3.4 and previous.
Problems: - GtkFrame widgets have no color. They do not show up at all now. This was the default in GTK3 for a while but I filed a bug and had it changed. - A 1px black line on all widget box borders. Very visually unappealing. Thunderbird shows this most visibly. - When you click on a application menu bar item the text changes to white. The menu bar is already white so the text essentially disappears. - The scroll bar used to be a close match to the GTK3 bar but now it looks like something from 1997. - The mouse-over color for GtkCheckBoxes is black. The whole widget and surrounding area turns black. - Buttons in Firefox are black (with black text!) until you mouse over. Just go to http://bugzilla.gnome.org and look at the buttons. You'll just see a black boxes.
QT apps use the GTK2 theme so QT apps are affected as well.
I would hope a bug for these issues was already opened, but if no one can point me to one I will open one.
Thanks, Michael
