研究方向
The issue is about the fallback value for SystemControlBaseHighAcrylicElementBrush used in battery saver mode. To fix, locate the brush resource definition in the WinUI resource dictionary files (e.g., generic.xaml or theme resources). The fallback value should be changed to a color that provides sufficient contrast against the acrylic background. Check the existing comment thread for any maintainer suggestions. Ensure the new fallback color matches the contrast guidelines for accessibility.
