Microsoft Addresses Windows 11 Bug Causing Red Tint in Games and Videos, Resulting in Frozen Content

Microsoft has acknowledged a notable issue affecting some Windows 11 users after the installation of recent updates, particularly the optional update KB5064081 released in August 2025. This issue manifests as a red tint on videos or games. Fortunately, a remedy is on the horizon, as it will be integrated into the upcoming optional update (KB5067036) scheduled for October 2025, and it is also set to be included in November’s Patch Tuesday.

The company clarified that while this issue might not be widespread, it has been observed in specific instances where videos or games exhibited a reddish hue. Although the term “red”is somewhat vague, it’s reasonable to infer that the graphics displayed an undesired red tint. The problem seems to stem from a potential bug in Windows 11 that disrupts color rendering, which might occur particularly during high-dynamic-range (HDR) content playback when the operating system attempts to modify color settings and increase brightness.

“After you install KB5064081, some videos and games might be unexpectedly red, ” Microsoft noted in the release notes, adding that the issue has been resolved.

Additional Rendering Issues with Full-Screen Applications

Another significant concern that caught the attention of many users, including myself, relates to a bug that hampers the rendering of onscreen content when a full-screen application operates in the background. During tests conducted by Windows Latest, we faced this issue first-hand. Specifically, while running a full-screen game, applications and browsers displayed erratic behavior; when scrolling through pages in Edge or Chrome, only certain sections would refresh, requiring cursor movements to trigger updates for the rest of the screen.

Initially, I suspected this might be linked to my Intel Arc GPU, given the frequency of Intel’s driver updates. Attempts to disable HDR and revert to older drivers did not yield any solutions. Eventually, it became clear that this was a Windows 11-related problem.

Microsoft later confirmed in their release notes that this bug indeed affects how screen content updates when full-screen applications are in use. The notification specified that, “Apps and browsers might display partially unresponsive onscreen content when other maximized or full-screen apps are updating in the background. This issue is particularly noticeable during scrolling, as only partial content refreshes.”Additionally, I created a video demonstrating this peculiar problem:

Microsoft also addressed a bug where text rendering issues occurred in applications such as Word or other online text editors. These resolutions are gradually being deployed across all users, but it’s important to note that merely installing Windows 11 KB5067036 or subsequent updates may not immediately resolve the issues unless you’re among the chosen few receiving the updates early. A broader rollout is anticipated to commence on November 11, coinciding with the Patch Tuesday updates.

Proceed with Caution Regarding the October Update

While the October 2025 update KB5067036 addresses these critical concerns, it has also inadvertently disrupted the functionality of Task Manager. Microsoft has acknowledged this new issue that prevents Task Manager from closing completely when the user attempts to exit, resulting in the program continuing to run in the background.

Details remain sparse regarding the root cause, but the tests conducted by our team revealed that the ‘X’ button intended for closing Task Manager fails to function properly, consequently leaving multiple instances running, which can adversely affect system performance. Microsoft has corroborated these findings and indicated that an upcoming update—likely to arrive on November 11—will include fixes for Task Manager alongside other improvements.
