About two days ago, Windows 10 Build 17046 was released for Windows Insiders on the Fast Ring for PCs. This build has got some hidden code for the upcoming new game bar with Fluent Design.
- The awkwardly small Prussian Blue Game Bar has been replaced with a much larger transparent—soon to be acrylic—bar
- The Game Bar now supports light and dark modes
- The entrance and departure animations have been refreshed
- The flipping Xbox Live avatar bubble is gone and replaced with a simpler Gamertag readout
- Shortcuts to your Xbox Live profile, Mixer profile, recordings folder, and settings have been added
- A clock has been added, reminiscent of the clock that appeared when opening Charms on Windows 8
- Some broadcast settings have been promoted to toggle buttons and switches on the Game Bar (e.g. capture video, audio)
