A recent update to Windows 11 has introduced an unexpected glitch, particularly affecting users who prefer dark mode. This issue causes the File Explorer window to momentarily display a bright white screen upon opening, which can be quite jarring. This article delves into the specifics of this bug, its impact on user experience, and potential workarounds, highlighting Microsoft's ongoing efforts to address the problem.

The problem stems from the KB5070311 update for Windows 11. Although Microsoft acknowledges the issue, it describes it as the window briefly showing a blank white screen before the files and folders load. However, user experiences suggest a more disruptive flashbang-like effect, especially for those accustomed to dark interfaces. This temporary white screen can occur in various scenarios, not just upon initial opening. It also manifests when navigating between 'Home' or 'Gallery' views, creating new tabs within File Explorer, toggling the 'Details' pane, or selecting more information while copying files.

The severity of this visual disruption appears to vary among users and hardware configurations. Some users report experiencing the flash consistently, while others, including a hardware writer who tested the update on multiple systems, noted that the flash does not always trigger. On larger displays, such as a 32-inch OLED monitor, this sudden burst of white light can be particularly disorienting and even distracting, leading to a less comfortable computing experience. Microsoft has confirmed that it is actively investigating the issue and plans to release more information and a resolution when available.

While Microsoft works on a permanent fix, some users might find temporary solutions to mitigate the annoyance. For those who are significantly bothered by this visual artifact and wish to avoid being, as one might say, an 'unpaid QA tester,' exploring alternative file management tools could be an option. Applications like Explorer++, though perhaps not as feature-rich as the native File Explorer, offer a functional alternative without the unexpected bright flashes. This allows users to maintain productivity and visual comfort while waiting for Microsoft to resolve the bug.
