Ok, thanks for trying that! I think you might be running into a CPU bug in the original Windows 10 1809 update (the one they pulled in late October). The system seems to come to a complete halt anytime something even slightly CPU intensive runs.

I had very similar issues to you, even without DisplayFusion running when I was on that build, and I actually ended up wiping my machine and re-installing 1803 :(


I am not entirely sure what happened. I had done reboots before without fixing the problem so I don't think that's it. But there has been a Windows 1809 cumulative update and an Nvidia driver update, and I'm not seeing the problem anymore. ]]> RE: Windows Explorer and DWM freeze and lag during wallpaper operations https://www.displayfusion.com/Discussions/View/windows-explorer-and-dwm-freeze-and-lag-during-wallpaper-operations/?ID=211f4b0c-04c8-45cc-bad3-c42886f93f49#4 Tue, 27 Nov 2018 16:15:36 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-explorer-and-dwm-freeze-and-lag-during-wallpaper-operations/?ID=211f4b0c-04c8-45cc-bad3-c42886f93f49#4 DisplayFusion Ok, thanks for trying that!

If you disable the "Use transitions when changing..." option in the DisplayFusion Desktop Wallpaper > Wallpaper Settings window, does that make any difference?


No it acts exactly the same way. ]]> RE: Windows Explorer and DWM freeze and lag during wallpaper operations https://www.displayfusion.com/Discussions/View/windows-explorer-and-dwm-freeze-and-lag-during-wallpaper-operations/?ID=211f4b0c-04c8-45cc-bad3-c42886f93f49#2 Mon, 26 Nov 2018 19:15:53 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-explorer-and-dwm-freeze-and-lag-during-wallpaper-operations/?ID=211f4b0c-04c8-45cc-bad3-c42886f93f49#2 DisplayFusion If you disable the "Use transitions when changing..." option in the DisplayFusion Desktop Wallpaper > Wallpaper Settings window, does that make any difference? ]]> Windows Explorer and DWM freeze and lag during wallpaper operations https://www.displayfusion.com/Discussions/View/windows-explorer-and-dwm-freeze-and-lag-during-wallpaper-operations/?ID=211f4b0c-04c8-45cc-bad3-c42886f93f49 Sun, 25 Nov 2018 00:24:37 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/windows-explorer-and-dwm-freeze-and-lag-during-wallpaper-operations/?ID=211f4b0c-04c8-45cc-bad3-c42886f93f49 DisplayFusion This might be related to this other topic:

I don't have an exact timeline but I believe it started happening with Windows 10 1809. Whenever the wallpaper switches the mouse cursor starts to lag like it's on ice. Windows Explorer reloads its desktop icons (they flash all white then come back). Dragging a window loses the lock on the window and it freezes in place.

I'm using an Nvidia 1080 Ti and an Intel 5960x. There's no apparent peaks in CPU or GPU use during the lag.

I have my wallpapers set to load random from a NAS over a network share. ]]>
