Hi,

I have an odd problem since doing a pkg upgrade earlier today. Since 
I've done that my laptop is painfull slow in XFCE but only when using 
the laptop without external displays. As soon as I plug in an external 
display it runs at normal performance. After disconnecting the external 
display it takes 1-2 seconds to respond to general typing and also task 
switching. Dragging windows around is also painfully slow. If I switch 
to a tty it is performant again as well.

Note this on a Thinkpad P1 Gen3 running hybrid graphics using both Intel 
and Nvidia. From memory when using external screens it switches to the 
NVidia GPU and uses the Intel when no external displays are attached (at 
least that's my understanding).

I have tried upgrading FreeBSD to the latest current. I have also force 
upgraded all packages.

Any help would be greatly appreciated.


Kind regards
Ben
