Wouldn't that cause similar problems with Windows? Or is the Windows graphics
driver more resilient to such problems? I personally haven't tried Windows, but
I saved the image so I could give it a try.

Unfortunately, Dell does not allow downgrading the BIOS. So we'd need a new
machine that is not yet updated. Which is difficult, since people do not come
here before they start having problems...
