screen freeze when attaching external screen through the dock.

Hi,

I have a buster laptop with gnome-shell (3.28.0-1). After doing a "apt
dist-upgrade", my laptop freeze when connecting to an external screen
through the dock.

It seems that the CPU start to go high, as the fan increase its speed.

Which file should I look to to better investigate the topic ?

Thanks in advance for the help.
