I'm using urxvt with the following .Xdefaults
urxvt.scrollTtyOutput: false
urxvt.scrollTtyKeypress:false
urxvt.loginShell: true
urxvt.scrollBar: false
urxvt.borderLess: false
urxvt.saveLines: 10000
urxvt.geometry: 84x26
urxvt.font: xft:Bitstream Vera Sans mono:size=9
urxvt.foreground: #cccccc
urxvt.background: #000000
!urxvt.inheritPixmap: true
urxvt.tintColor: #ffffff
urxvt.shading: 100
Transparency is fine but shading/tinting doesn't work anymore.
The background used to be darker "under" urxvt so that the text was easily readable everywhere but then suddenly tinting/shading "got lost".

The problem ist I don't know what caused it. I didn't do anything special that day, then I changed my WP therefore restarted X and I noticed that Shading/Tinting didn't work anymore.

What maybe the reason for that? I've got no idea where to start searching.

Any assumptions or ideas where to look/ask etc.(in short:everything) are welcome!
