In Windows 10 2004, however, movement in the secondary display does not seem to cause any stutters the Test UFO page indicating that Microsoft could have finally fixed what has been an ignored issue since the times when DWM was made an integral part of Windows since Windows 8.Įven if you don't have two monitors, the issue can still be replicated when you run a game in borderless windowed mode and have another window by the side. In the OP's video (which we have uploaded to YouTube and embedded below), one can see the Blur Buster's Test UFO page in the 144 Hz monitor (left) reporting major stuttering when the Explorer window is moved in the secondary 60 Hz monitor (right) in the case of Windows 10 1909. Reddit user /u/loopy750 uploaded a video to demonstrate the difference in refresh rate sync between Windand an Insider Preview version of Wind(Build 19041.2004). Therefore, the monitor with the higher refresh rate gets pulled down to match the lower refresh rate monitor causing micro-stuttering and frame-skipping.

This is because the Desktop Window Manager (DWM) - the display compositing component of Windows - draws on both monitors together instead of individually compositing each display. If you have ever used multi-monitor setups with differing refresh rates, say 144 Hz and 60 Hz, any window movement in the 60 Hz monitor meant that stuttering would be observed even in the 144 Hz display as well until the window movement is stopped. Those having multi-monitor setups with different refresh rates for each monitor will find a good-enough reason to update their PCs to Wind20H1.

However, it looks like the update solves a niggling issue that has been plaguing Windows users since the days of Vista Longhorn. The upcoming feature update to Windows 10 has a decent changelog but does not offer much in terms of totally new features.
