• Desktop background image. Recent Canary builds added the ability to use .webp format images as desktop backgrounds via Settings > Personalization > Background. This allows using more compact images without noticeable loss of quality.
• System stability and quality improvements. The update includes a small set of general improvements and fixes aimed at increasing stability and overall system quality for insiders using this build.
• Fix for dialog box cropping. Fixed an issue where the edge of the warning dialog box when shutting down the PC (if other users are active on the system) was cropped by the Start menu border.
• Fix for screen flicker when drawing with a pen. Fixed an issue that could cause brief black screen flickering when using a pen to draw or annotate in the Snipping Tool app.
• Fix for false reboot during shutdown. Fixed an error in recent Canary builds where on some insider devices the system shutdown process appeared as a reboot.
• Fix for Windows Update page freezing. Fixed an issue where the Windows Update page in the Settings app could freeze while loading.
• Fix for loading language components for Australia. Fixed an error where language components in Settings > Time & Language > Language & Region for the Australia region (English – Australia) would not load — the download button did not respond.
• Fix for blue screen error IRQL_NOT_LESS_OR_EQUAL. Fixed an issue where a small number of insiders in recent builds encountered a blue screen (BSOD) with error IRQL_NOT_LESS_OR_EQUAL related to using certain smart card readers.
