Bugs and quirks[edit | edit source]

General[edit | edit source]

  • Some games that use Easy Anti-Cheat may crash or cause the device to bugcheck.
  • Shutting down Windows via the Start menu may unexpectedly reboot the device in some cases.
  • Surface Pro X devices may hit a black screen when attempting to resume from hibernate in this build.

Live captions[edit | edit source]

  • Certain apps in full screen (e.g., video players) may prevent live captions from being visible.
  • Certain apps positioned near the top of the screen and closed before live captions is run may re-launch behind the live captions window positioned at top.

Safe mode[edit | edit source]

  • Quick Settings and date/time clock on the taskbar may be missing due to the Capability Access Manager Service service not running.
