Slowness after System on for extended period of time

Brian D.
4 discussion posts
Hi,

Ive had this issue on my older W7 system but persists on my new W10 (different hardware). I know DisplayFusion is the issue as I can exit the program and performance returns to normal.

Most issues come in the form of delays and windows of programs such as Word taking a long time to move monitors of which there are 3. Also browser windows suffer the same fate. Rebooting fixes the issue for about a week or so and then its back to the slowness and pain.

Any help is appreciated, I dropped my logs below.

Hi Brian,

Just a quick note, this is a public forum, so I've removed the troubleshooting info section of your post for security reasons. If you would like to send us over the file itself, that will stay protected and we can have a look at it

If you exit DisplayFusion when the issue happens and re-open it, does the issue come back right away, or does it take another week?

Thanks!

Hi Owen,

Thanks and sorry. When I close DF and reopen the slowness picks up where it left off, same sluggishness. See attached

Hi Brian,

When the issue happens, if you open Task Manager, is DisplayFusion using a significant amount of any resource?

Thanks!

I did notice that after you mentioned that moving a window from screen to screen makes CPU utilization spike from about 2% (idle) to about 7-10%.

I'm seeing this as well. I just purchased/downloaded/installed a few days ago and it's been OK until today. I noticed that scrolling, resizing, and moving windows is very choppy/laggy. Even typing this post the text stops and catches-up after a few seconds.

The only out of the ordinary thing I did was I connected to this workstation from another via RDP yesterday. So, when I logged-in today Windows had to re-sort all the Windows out. This is something that I do regularly, but the first time since installing DF.

Task manager shows that DisplayFusion is using a constant 1%-2% and closing DF resolves the issue instantly. Upon relaunching DF the issue happens again.

Specs:
Windows 11 Pro build 22526
DisplayFusion Pro 9.9
Xeon W-3245M
96GB RAM
4 x Monitors
- 2 x Dell 38" Ultrawide
- 2 x HP 1440p
Nvidia 1060

It seems that after a full reboot of my workstation the issue has been resolved - I'll update on how long it takes for the slowness to present itself again.

Hi Brian,

Interesting, so if the window is just sitting it's fine, but as soon as you drag it, the CPU spikes for DisplayFusion?

Thanks!

So I did a small test and used one monitor to 'violently' move the browser window around as fast as I could, staying within the same monitor (By moving the mouse very quickly). It did lag as usual but I was able to get the CPU usage to spike from about 1-2% idle to about 8-9% during the most aggressive of the window moving. This is about a 300% increase but whether or not this is the cause Im unsure.

Moving from monitor to monitor normally goes from 1-2% to about 4-5% of CPU usage.

Is there some sort of performance setting within DF we can adjust to try and mitigate the slowness?

Hi Brian,

Can try disabling tiltebar buttons via the DisplayFusion Settings > Functions > uncheck "Enable Titlebar Buttons", and see if that helps?

If there's no change, can you also try disabling Window Snapping in the DisplayFusion Settings?

Let me know if either of those help.

Thanks!

It could be unrelated but I've noticed the secondary taskbar crawling after some time. Right click menus taking a very long time to load. Things like that. Windows 11. Restarting DisplayFusion always fixes it. CPU usage is under 1%
