In updated to W10 1803 tonight and updated to the Radeon 18.4.1 drivers. Things seem to run fine on the new stuff EXCEPT when I launch any mixed reality stuff. The screen will flash several times and I will eventually get a message that the drivers failed to load and Windows will use its basic driver. The Radeon settings panel says no radeon drivers are loaded. A reboot restores the AMD driver until the next time WMR is attempted. I tried several reinstalls to no avail. "The display driver failed to start; using Mcrosoft Basic Display Driver instead. Check Windows Update for a new driver." Of course, there is no newer driver there.
