I've had a similar issue; can't see any highlights hovering over things anymore (i.e. tray icon for pulseaudio or network manager, can't adjust things in pulseaudio window, etc). On Mon, 11 Apr 2016, Ralf Mardorf wrote:
Hi,
after the last upgrade GTK2 apps running in an openbox session need more space, they became darker and in some windows even the fonts became less good readable. The reason that I dropped desktop environments was to get rid of chaotic designs and to keep a clear design and now even GTK2 apps in an openbox session became a parody.
I'll downgrade one package after the other, but perhaps somebody could give me a hint what package/s might have caused the new unfavourable look.
One problem is shown here, a dilettante repeated unnecessarily design, e.g. a bar that already separates regions inside a window, became a bar with a cutting line inside the bar:

The list of packages that were upgraded is posted here:

[rocketmouse@archlinux ~]$ grep -v '#' .gtkrc-2.0
gtk-theme-name = "Adwaita" style "user-font" { font_name="FreeSans 12" } widget_class "*" style "user-font"
