Using Radeon or Nouveau can cause incorrectly rendered graphics
A bug in the Xorg server can, under rare circumstances, cause graphics to be rendered incorrectly if using the Radeon or Nouveau graphics device driver. For example, the Thunderbird message pane can be displayed incorrectly.
For Nouveau, as a workaround, add the
WrappedFB option to the xorg.conf file as follows:
Section "Device" Identifier "nouveau-device" Driver "nouveau" Option "WrappedFB" "true" EndSection
This workaround avoids the faulty logic in the X server, and the Thunderbird message pane will be displayed correctly. (BZ#1076595)
