Details

Description:
Xvfb shows wrong colored (e.g. black or grey) pixels instead of transparent when 8-bit color depth is set.

Additional info:
* xorg-server 1.7.5.902-1
* x11vnc 0.9.9-1

Steps to reproduce:

Open terminal and issue following commands:

export DISPLAY=:1
Xvfb :1 -screen 0 640x480x8 &
openbox &
x11vnc -display :1 -bg -nopw -listen localhost

Open another (!) terminal and issue:

vncviewer localhost

You can see new VNC viewer window on the screen.
Right-click the mouse somewhere within blank area of that window.
In the drop-down menu select Editors -> GEdit, and you will see the picture similar to one in attached file.
Note that should you change 'x8' to 'x16' snippet in Xvfb command above, GEdit look become normal.
This task depends upon

JGC: what to do with this one?
Looks like upstream issue.

Is this still a problem? Has this been reported upstream?
Comment by Pavel (heavyrail) - Friday, 04 March 2011, 07:19 GMT
Yes, it is still a problem. I reported it upstream long ago, but no one answered me there:
