Please see the attached log file and screenshot.

My DisplayFusion settings have not changed for several years. However, over approximately the past year, DisplayFusion has become increasingly unreliable and has started causing recurring issues.

I only use a small portion of DisplayFusion’s functionality, so it would be useful if DisplayFusion offered modular installation options instead of requiring the full product installation. In my case, most of the installed features are never used, but the full product still appears to contribute to reliability or overhead concerns.

Expected behavior:
DisplayFusion should remain stable with unchanged long-term settings.

Actual behavior:
DisplayFusion has become progressively unreliable despite no intentional configuration changes.

Environment
Application: DisplayFusion
Process: DisplayFusion.exe
Observed process ID: 48948 in the provided System Informer screenshots

----

TL:DR
Additional diagnostic finding
Temporarily disabling TitleBar Buttons reduced DisplayFusion CPU usage, but high enumeration activity continued afterward. This indicates that the TitleBar Buttons subsystem is likely contributing to the high CPU condition, but it does not appear to be the only source of repeated work.

The remaining activity suggests another enumeration path may still be active, possibly involving service IPC, module inspection, taskbar or tray icon enumeration, monitor enumeration, hook polling, or window-state refresh processing.

This should not be treated as resolved by disabling TitleBar Buttons. The broader issue is that DisplayFusion continues to perform excessive repeated enumeration under a long-standing configuration that previously operated acceptably.

----

Summary
DisplayFusion.exe is exhibiting high CPU utilization and heavy runtime thread activity. The issue has existed for some time and has progressively worsened. The current evidence shows DisplayFusion.exe consuming approximately 51% to 73% CPU in captured states, with overall CPU load near saturation.

Observed behavior
- DisplayFusion.exe appears as the dominant CPU consumer.
- CPU meter shows very high total CPU activity.
- System Informer thread view shows many active DisplayFusion.exe threads associated with coreclr.dll.
- Repeated thread start addresses include coreclr.dll+0xcccc40.
- Multiple entries also reference coreclr.dll!KickOffThread.
- System Informer statistics show elevated CPU, CPU relative, cycle delta, and context switch values.
- DisplayFusion settings have not intentionally changed for several years.

Expected behavior
DisplayFusion should remain stable as a background utility and should not produce sustained or excessive CPU load under an unchanged long-term configuration.

Actual behavior
DisplayFusion.exe generates high CPU load and appears to create or run many active .NET runtime threads, degrading system responsiveness.

Evidence
- Screenshot 1: DisplayFusion.exe at approximately 51.45% CPU.
- Screenshot 2: DisplayFusion.exe thread list with many active coreclr.dll+0xcccc40 entries.
- Screenshot 3: DisplayFusion.exe thread list with multiple coreclr.dll!KickOffThread entries.
- Screenshot 4 through 6: Loaded module views showing DisplayFusion, .NET runtime, Windows Forms, scripting, hooks, and related dependencies.
- Screenshot 7: Process statistics showing elevated CPU-related counters and memory footprint.
- Screenshot 8: DisplayFusion.exe at approximately 73.39% CPU while total CPU is near saturation.

Impact
The issue causes recurring system performance problems and reduces confidence in DisplayFusion as a stable long-running utility.

Probable fault surface
- DisplayFusion background worker loop
- .NET runtime thread scheduling
- Hook or monitor polling logic
- Scripting subsystem
- Window management or monitor event handling
- Repeated event processing
- Excessive timer, observer, or polling activity
- Interaction with WMI, monitoring tools, hooks, or multi-monitor state ]]> RE: Display Fusion causing major lag in games when moving mouse. https://www.displayfusion.com/Discussions/View/display-fusion-causing-major-lag-in-games-when-moving-mouse/?ID=0197e653-607a-712b-b589-bcdee0afe8a1#8 Wed, 29 Apr 2026 19:41:04 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/display-fusion-causing-major-lag-in-games-when-moving-mouse/?ID=0197e653-607a-712b-b589-bcdee0afe8a1#8 DisplayFusion Here you go, hopefully you guys can figure it out!

Any suggestions?

Right click the desktop, choose personalise, set a picture. I was honestly not aware that DisplayFusion had the ability to control the wallpaper, and I certainly never KNOWINGLY activated that option myself.

However, that was the information I needed. I have turned that option off, and my wallpaper now functions as I would expect it to.

On Windows 11, unfortunately, it does more harm than good.
As soon as it is installed and an alternative editor (e.g. Notepad++) is set, all files that were originally associated with the new Windows 11 Editor stop working. Worse still, Notepad Replacer 1.6c simply uninstalls the Windows 11 Editor without asking.

It would be great if this could be fixed. At the very least, there should be a confirmation prompt before uninstallation.

5. Yes, and when I go into fullscreen it has three states:

a. Shows taskbar only on right side of screen (my taskbar setup is 1/4 (windows one here) 2/4 1/4
b. One taskbar throughout the app
c. No taskbar but when my mouse goes down there it flickers the fullscreen app on/off (looks like this is the taskbar trying to pop up as it only happens when I have mouse at the bottom which unfocuses the fullscreen app therefore flickering off it to desktop).
