Dark mode broken, Intel Arc GPUs BSOD

The December preview update turned dark mode into a light show. File Explorer flashed white screens and went blank when dark mode was enabled, defeating the entire purpose of the feature. Intel Arc B580 GPU owners got Blue Screens of Death. Installation failures hit with error 0x80070306. The password icon on the lock screen became invisible — a recurring Microsoft favorite. Performance slowed to a crawl. At least the dark mode issue was fixed quickly in December’s Patch Tuesday, because nothing says quality assurance like shipping a preview update that breaks a basic display preference.
