[John Landmesser]

..reminds me at a bug in intel Drivers i had trouble with on Linux-Mint

I have a Intel GPU, and i have these annoying black windows.

But you can do it this way:

create as root the file /etc/X11/xorg.conf

in terminal type ( if you don't have a /etc/X11/xorg.conf ) :
sudo touch /etc/X11/xorg.conf

open editor in admin mode:
gksu gedit /etc/X11/xorg.conf

... and write/copy these lines:

Section "Device"
Identifier "Card0″
Driver "intel"
Option "AccelMethod" "sna"
EndSection

reboot

if that doesn't help do in terminal:
rm /etc/X11/xorg.conf
to delete it again


seems to work ok for me, but i have to test this some days first.

update: 10.07.14
..still working ok!
That was the solution for these annoying black pop-up windows!!
