I recently upgraded to dual 4K monitors (for reference, my monitor setup is a Cintiq 22HD and 2 4K monitors). Whenever I wake the computer up (moving the mouse after the screens have gone black from inactivity), the wallpapers always mess up and sometimes load up in the wrong monitors and my mouse (wireless Logitech M570) will lag badly. Sometimes it will correct itself after a few minutes, but lately I've noticed it seems to correct if I open the Task Manager, which doesn't make any sense to me. I didn't have any issues prior to the 4K monitors, so I'm not sure if my problem is related to DisplayFusion, Windows 10, or a mix of both. I am using Display Fusion Pro 9.1.

EDIT: It also looks like Display Fusion is consuming about 15-25% of the CPU when this happens (at normal use, it's usually 1% or less).

Hello. Disabling the multi-monitor taskbars has just about eliminated that problem in my testing thus far. Is the multi-monitor taskbar the likely culprit then? This was after manually setting the computer to sleep.

EDIT: Did not solve the problem as I thought. Though the lag problem isn't as bad as it was and it doesn't take as long to straighten back out, it still takes longer than I think it should. Multi-monitor taskbar is still disabled. This is what occurs after moving the mouse to wake the computer up (computer is still on, just in light sleep mode from inactivity).

This is another thing that occurs sometimes when waking the computer up.

The mouse lag occurs for as long as it takes for Display Fusion to get everything straightened out. This wasn't an issue when I had all 1080p monitors, but it became one once I upgraded to 4K monitors.

Here is the info requested today.

Disabling the wallpaper minimizes the amount of time the mouse lags when waking up the computer (down to just a few seconds), but it always occurs when waking the computer from a sleep state or dormant state. The taskbar doesn't always jump to weird places, only on occasion.

Under processor power management it says:
- Minimum processor state setting: 5%
- System cooling policy setting: Active
- Maximum processor state setting: 100%.

That makes no difference. It is still laggy and takes a few seconds for the screens to correct themselves as before when waking up from an inactive state.

Did not make a difference.

I only have DisplayFusion issues whenever waking up the computer from an idle state (such as when the monitors have gone blank from inactivity, but the computer is still on). I don't have any issues any other times with it.

Hello! I apologize for my lack of response. I have just downloaded and installed 9.3c. I will test it over the weekend and see how it does.
