Created attachment 6299 Some colors are used form theme set in Settings->Appearance instead of the one set in GTK2_RC_FILES I found the bug on Manjaro (it's the same on Arch on a different machine) with the default theme (Menda) when I tried to start Eclipse with a dark theme (Menda-Dark). The bug isn't Eclipse specific, it can be observed in many other apps, including gtk-demo (see attached screenshot). I only assume this is an xfce bug (although I'm not sure witch component could cause this) because the same thing works with Openbox. Steps to reproduce: Set the theme to Menda through Settings->Appearance. Run this from the terminal (path might be different on other distros): env GTK2_RC_FILES=/usr/share/themes/Menda-Dark/gtk-2.0/gtkrc gtk-demo Expected results: Uniform dark backgrounds on all wigets. Actual results: Some colors used are from the globally set theme.
I copied the gtk-color-scheme definition from Menda-Dark to Menda and after selecting Menda in Settings->Appearance the result looked exactly the same as on the attached screenshot. It seems like the whole gtk-color-scheme gets overridden by the theme set in Appearance.
Closing old bugreports, xfce is now gtk3
