Now is the third year as I have problem with divers. I did ask on X11
mailing list, in the Forum, on github but it doesn't work. It worked
on 11,1 FreeBSD and no more. Just black screen. But to the week or
something ago I didn't have a problem to work with FreeCAD with scfb
driver. I will try to downgrade qt5-opengl because I think all the mess
started with this update. BTW I am using Openbox.
Thank you.
