Just upgraded to Fedora 15 this afternoon, and for the most part there weren't any serious issues with it (except for rpmfusion lagging on a F15 yum repo).
I installed the XFCE spin, and a lot of GNOME-specific apps don't respect my GTK+ theme at all.
On the left are two "XFCE" apps (Mousepad and Task Manager), on the right are two GNOME apps (gedit and the NetworkManager "Connection Information" window).
Is there an easy way to fix this? I have a custom Murrine theme set, but the problem is still there using the built-in themes such as Glossy too.
It seems like the only theme that works is the Adwaita theme.. this apparently is the only default theme that has a gtk-3.0 folder in it (the high/low contrast themes do too, but the others don't work with gtk-3.0; Raleigh has a gtk-3.0 folder but the theme doesn't affect gtk3 apps).
