The problem persists. According to the Magix helpdesk it is caused by a driver conflict for the internal Intel UHD 630 and the Nvidia GTX 1050 Ti with max design; both part of the Dell XPS 15 9570 laptop.

Dell affirms that the Magix helpdesk could be right. But their attempts to help did not solve the problem.
The proposed solution: deinstalling the graphic drivers with DDU and then reinstalling them.
Does not work.
Anybody with a better solution?
Is there anybody out here running Vegas Pro 16 on a Dell XPS 15 laptop? Did you encounter the same problem and if so, how did you overcome the problem?
