I recently upgraded to 14.04, and after a little bit of fighting, I got my 4-monitor setup "working". However, a few applications (I've noticed gedit and SublimeText), will have the entire window blacked out when it loses focus. Once it's blacked out, I cannot get it to show again without restarting the app. Just to be clear, this makes the applications unusable.
My setup is using the nVidia proprietary driver version 331.38, on a Quadro NVS-450. Below is my xorg.conf file, and following that is the output of /usr/lib/nux/unity_support_test -p
. Any ideas what's going on here?
