Hello,

I just encountered mouse lag problem again in DisplayFusion 9.7.1 beta 5 with Windows 10 20H2. I'm wondering if there is anyone that having the same problem?

After DisplayFusion exit then everything works fine again. Any suggestion is highly appreciated!

Hi,
Same symptoms for me with Windows 20H2 (19042.610).

Hi,
I was 9.7.1 beta 4.

Hello,

I didn't have 9.7.1 beta 4 executed on Win10 20H2 yet and don't have installation package now. I could try it if you could provide a 9.7.1 beta 4 download URL.

Hello,

Thank you for releasing 9.7.1 beta 4. ust tried to install it with all default settings, I didn't discover the mouse lag symptom.

Agreed ...
I was experiencing periodic mouse lag in DF 9.7.1b5 (WIndows 10 Pro).
Did not experience this in DF 9.7.1b4.

Downgraded DF to 9.7.1b4 and enjoying mouse lag free experience

Also had same experience with 9.7.1 B5
Upgraded from 9.7.1 B4

I noticed mouse and screen freeze briefly every 5-6 seconds, then fine until next freeze.

Great product! I downgraded to 9.7, but with the link you provided I am going to upgrade to 9.7.1 B4

9.7.1 beta 4 works fine with no lag.
No logging enabled while using beta 5.

Sorry I didn't notice about that. I didn't try to adjust such feature/setting when I was using beta 5. The logging setting should be remained as default value.

I'm having the same issue with mouse lag on 9.7.1 beta 5 but my Windows version is 20H1.

9.7.1 beta 6 did not fix the issue for me.

Downgraded back to 9.7.1 beta 4 and the problem is gone.

Hi,
Installed beta 6: issue exists
Disabled System Hooks (Polling): issue persists
Regards

Reloaded beta 6 and enabled "Disable System Hooks (Polling)".
Restarted DisplayFusion but the lag was still there.

I also have the same issue in 9.7.1 beta 6.
Attaching minimal and detailed log files.
Both of these logs were taken without disabling System Hooks.

9.7.1 beta 6, Disabled System Hooks
Attached: Minimal log + DebugInfo + exported settings.

same, reverted to 9.7 immediately

Hi,
Installed beta 6 and disabled all 3 hooks: mouse lag is still present.
By the way, I suspect the lag to impact not only mouse but the whole display as task manager is also frozen when the mouse is irresponsive.
Regards,

Update to beta 6.
Reactivate all hooks.
Reboot.
No lag so far

This morning, with no specific reason, the app seemed to relaunch.
Since then the lag is back so I have quit.
Hopefully it will stop lagging after restart, I will post on that later.

Confirmed,
After reboot, my beta 6 with all hooks activated has no lag issue.

So, the lag suddenly appears and can be stopped by quitting Display Fusion beta 6.
After a reboot, no lag until the next issue.
And so on...

This is all very interesting.. I couldn't work out what was causing my lag of mouse and display etc... But am seeing the same thing with 10 20H2 and 9.7.1 Beta 6. I was actually looking for issues with Taskbar on my second screen, appearing over the top of windows which are set to maximum. This is especially annoying with Edge or Chrome.

Happy to do some testing on this also.
To be honest, it feels like it has been happening for months.
I've had betas for ages, but didn't click.

Hi Owen,

Just to confirm, that since turning off:

Disabled System Hooks (application, Polling and Shell), my system has been running much better.

Please note, that it isn't just Mouse Lag, it relates to Windows and Applications when they are moved around.

Very happy to have been able to replicate it. Look forward to reading the release notes for future releases.

Andrew.

Hi Owen,

Thanks, beta 7 fixed the mouse lag issue that I was seeing.

I don't know if this is related, but I see a similar lag when opening the settings page. During the time the splash screen is playing, the system repeatedly lags. Once the splash screen is gone the lag stops.

Thanks,
Steve

Every time

Hi, I also experiment the lag when opening settings but that exists for a long time. Never reported it as it is not so big a trouble.

It's a desktop

Here you are.

Disabling system hooks fixes the lag ... but then my title bar buttons don't stay with the title bar precisely when I move a window around.

System hooks on still creates mouse lag 9.7.1b10

Hi all,

This seems to have come back with 9.8? Anyone else notice.. I've just gone back to disabling the Hooks.. I'll see how that goes..

Andrew.

I also have nasty Mouse Freezing issues with the most recent version of DF Pro. As soon as I turn off the program the issue is gone. Can I upload some debug info for you?

Still having problems. No issues with CPU usage. I'll need to try it again with DF turned off altogether.
I think my home machine has upgraded to 21H1, but I'll have to check when I get home tonight.

Andrew.

I will try this too. It's a i76850k Desktop machine in my case. I'll set the minimum to 10% for testing.

Hi Owen,

System was back to normal after removing DF.
My system is always set to 100 min and 100 max..

AMD 3900x, 32GB Ram, Samsung 860QVO SSD. Nvidia 1080.

Andrew.

Yup, I will have an eye on this and hope that I won't forget reporting I had made the change one Wednesday and saw no issues yesterday, but I'd like to check for a week to be sure.
