Title: Microsoft Patches Annoying White Flash in Chrome and Edge Dark Mode on Windows
Introduction:
For years, users of Windows 11 and Windows 10 have endured a persistent and irritating visual glitch: a jarring white flash when opening new windows or launching Chrome and Edge browsers while in dark mode. This seemingly minor issue has been a constant source of frustration, stemming from a fundamental disconnect in how Windows and Chromium-based browsers handle dark theme window creation. However, relief is finally on the horizon. Microsoft has developed a patch that promises to eliminate this annoying visual hiccup, offering a smoother and more consistent dark mode experience.
Body:
The root of the problem lies in the way Windows’ Desktop Window Manager (DWM.exe) initially renders new windows. As browser researcher Leo discovered on X, when a new window is created, Windows defaults to a white background before the browser takes over and applies its dark theme. This brief period of white display creates the unwelcome flash. This issue is not exclusive to browsers; similar white flashes have been observed in File Explorer before it fully loads.
Microsoft’s solution, spearheaded by web team developer Chris Davis, is a clever workaround rather than a complete overhaul of the DWM.exe. The approach involves hiding the window during its initial creation phase. Davis explains, When a window is first created, DWM uses a default white background color for it. This causes a white flash when the window is first displayed in dark mode. To avoid this, we hide the window before it’s first displayed, force it to draw the intended background color, and then unhide it.
Essentially, before the window is visible, the browser forces the intended dark background to be rendered. This prevents the brief flash of white from ever appearing. While some Chromium code contributors initially expressed concerns about potential race conditions – where the GPU might not finish rendering the content before the dark background is applied, leading to a brief display of the underlying content – Microsoft’s testing has shown this not to be an issue.
This fix is not a permanent solution to the underlying problem with DWM.exe, but it is a practical and effective measure to address the immediate frustration of users.
Conclusion:
The upcoming patch, which will be implemented in both Chrome and Edge, marks a significant step forward in improving the user experience on Windows 11 and 10. While it doesn’t address the core issue within Windows’ DWM, it provides a much-needed respite from the annoying white flash. This fix demonstrates Microsoft’s commitment to addressing user pain points and ensuring a more seamless and visually consistent experience, particularly for those who prefer dark mode. The change is expected to roll out to users soon, bringing an end to this long-standing annoyance.
