Windows 10 users have been plagued by a long-term problem that has been an annoyance for multi-monitor users. Specifically, there was a problem when users were connecting with more than one monitor. Microsoft has now rolled out a fix.
As first shared on Reddit, users running Windows 10 have experienced a screen stutter problem in multi-monitor mode. Amazingly, there have been reports of this issue extending back more than a year.
Microsoft says the issue was caused by the window management tool DWM, which is embedded into Windows 10. This tool is used to allow the platform to support hardware acceleration to render the graphics on Windows.
For users running dual monitor situations, when the second (or third) screen was added, the frametimes would drop and the screens would stutter. Sometimes, users report the secondary monitor would not show anything.
Microsoft has now fixed this problem according to the Reddit page. However, the fix has so far only been rolled out to Windows Insiders. It is bundled into a patch for Windows 10 20H1. This means you will need to wait until 20H1 arrives this spring to receive the fix as an end user.
Recent Update Problems
At the end of last week, we reported on Windows users facing various problems following Microsoft's February 2020 Patch Tuesday security updates. Problems ranged from files going missing from the desktop to systems not booting following the patch. Regarding the latter issue, Microsoft says it has now removed the security update that caused it.
Microsoft yesterday halted the individual update that was causing the problem. Labeled KB4524244, the security update was rolled out across all Windows 10 versions last week. It was launched to fix a vulnerability in the non-Microsoft Unified Extensible Firmware Interface (UEFI) boot managers.
