Do you have the compositor enabled in xfwm4? 

Xorg 6.8.x had some bugs that would make it unsuitable for use with xfwm4 compositor. There is a check for that in xfwm4 4.4 that automatically disable the compositor when using Xorg <= 6.8.x, unless the user forces the "--compositor=on" option on the command line.

Also, I've read (but not experienced myself) that the recent versions of VTE have some bugs that could match your description. Terminal uses ARGB32 windows to achieve true transparency when a compositor is running and it seems there could be some regression in VTE in this regard.

Cheers,
Olivier.
