Hi quiet list,
   This is a request for anyone using Chrome, any version in portage -
I've tried stable, beta and unstable - to see if you see this problem.
It's easy to reproduce on my system.

   The system I've got:

1) Gentoo 64-bit, mostly stable
2) Two NVidia 8400 GS VGAs driving 3 monitors using nvidia-drivers
3) KDE with 6 desktops + 3 screens/desktop

First, demonstrate no basic problems: open Chrome and move it around
to different screens on any desktop. Chrome should work fine as it
does here.

Second, demonstrate the problem. In the Chrome menu in the upper right
- 3 horizontal lines - choose New Window. Chrome pops up and looks
good. Move it to another screen and see if it turns black. It does on
my system.

   The Chrome folks are looking for some verification in a bug report
I made here:

https://code.google.com/p/chromium/issues/detail?id=443189

   If you see the problem maybe you can add some info to the bug
report. If you do not but have some ideas about how I might
reconfigure something like X to fix this I'd appreciate hearing your
ideas. I'm attaching my xorg.conf file if someone wants to review that
for possible fix-ups I might try.

Thanks,
Mark
