The update resolves an issue with incorrect refresh rates being displayed for high dynamic range (HDR) displays, while flickering on video playback on certain low latency monitors has also been fixed. Similarly, issues preventing the input of strings into the Input Method Editor (IME) or preventing some keyboard keys from working (such as the home, Ctrl, or left arrow keys) when you set the Japanese IME input mode to Kana have also been resolved. Microsoft has also included fixes for screen rendering while opening games on certain unspecified hardware configurations, and an issue with incorrect languages being displayed when you sign into a console and modify the system locale. Another bug with unexpected screens showing up during the Windows Out of Box Experience (OOBE) setup screens has also been resolved.
