Broken display driver after update

The Adreno X1-85 identifies the Snapdragon version of Surface Laptop 7, so use its Surface driver package rather than selecting an incompatible adapter from Device Manager’s list. Reinstalling the same display driver does not test the rest of the Surface display stack.

First, test Microsoft’s documented brightness setting: Settings > System > Display > Brightness > Change brightness based on content > Off. Note whether the blinking and Night light changes continue. Next, confirm the exact model and Windows build, then install the matching Surface Laptop 7 Snapdragon drivers-and-firmware MSI from Microsoft and restart, if that package has not already been applied.

If it persists, check whether flickering also occurs in Surface UEFI without changing settings. Flickering there suggests hardware rather than a Windows driver. Otherwise, give Surface Support the update date and driver versions for targeted recovery guidance; an announced fix cannot be assumed.
