Microsoft has released a new Windows 11 release preview build that finally fixes the annoying white flash bug in File Explorer's dark mode, a problem that has been ongoing for over two years. The issue was initially thought to be resolved in 2023, but a subsequent update reintroduced the problem. The latest fix removes the white flash when launching File Explorer in dark mode under certain conditions.

💡 Why It Matters
