Starting today I have see Display Fusion Pro eat up 100% CPU on one core, and memory is growing quickly. It becomes unresponsive and I have to kill the process and restart.

Display Fusion Steam Version 7.1

Restart doesn't fix it. Uninstalled anti-virus, no effect. Nothing has changed on the system from Saturday to today.

I noticed that you're running 7.2 Beta 1, which isn't officially released yet. Did you grab that from the forums and install it before or after you started having the CPU/memory issues?

I saw that in another thread, so I tried it after.

Strangely, the day after I posted this, the problem randomly stopped. I have no explanation. Nothing changed before it started. Nothing changed before it stopped.

Ok, that's really strange! If you do run into trouble again, just let me know

Thanks!

Also, I'd recommend re-downloading and installing the 7.2 Beta 2 that we posted yesterday (http://www.displayfusion.com/Download/Beta/), as we made some more critical changes after we posted that test build in the forums.

The problem has sort of resurfaced.

It's not crashing like it was previously, but its now eating up 100% of a CPU core.

I'm going to install Beta 2 that you linked and see what happens.

Sounds good, thanks! Does this issue creep up over time after DisplayFusion has been running, or does it do it as soon as DisplayFusion starts up?

Sorry, been a busy couple of months.

Updated to the Beta of 7.2
Performance issue still happening. It's eating 100% of one CPU.

I've been having similar problems. I'm running 7.1 Pro on Windows 7 Enterprise (64 bit dual core 2.8GHz with 228G - 4G free). My system is dual monitor, both wide screen. I have a personal background image that spans both screens and other custom settings.

I notice that usually after running either a Virtual Machine session or in some cases using conferencing software (MS Lync), that my system slows way down and becomes unusable. Sometimes if I go to lunch it may recover by the time I come back, but usually I do a hard power-cycle to reboot because the response doesn't even allow me to restart gracefully.

I've noticed when I run some diagnostic tools (Process Explorer, etc.) that DisplayFusion is up there in CPU and memory utilization (even when nothing is happening on the system). I've seen CPU running generally around 10-25% with spikes and memory consumption in the 100+M.

I don't know if this is the cause or just being adversely affected by another program - I haven't tried exiting DF when these situations occur - that will be my next test.

Could you guys do the following for me?

In Sysinternals Process Explorer, open the Properties of the DisplayFusion.exe process
On the Threads tab, take a screenshot so we can see which threads are running up the CPU
Click the Thread that has the most CPU usage, and click the Stack button
Click the Copy All button and save that to a text file
Attach the screenshot and text file here

Thanks!

When I click on Stack, it says "Unable to access thread"

One more thing I discovered
The service "Service Host: Local Service (Network Restricted)" Service is using 25 Mb/sec of disk activity
If I kill DisplayFusion, that drops to a more reasonable level of around 2-3 Mb/sec

Currently that service is churning 50 MB/sec on my HDD

Ok, that's really bizarre. I can't imagine what DisplayFusion would have to do with any of those services that are run in that instance of svchost. If you startup DisplayFusion again, can you stop each of those services (from the Services console) one by one and see which specific one makes the disk activity go back down to normal?

It's the Event Logs

As soon as I stop it, it starts up again, but if I disable the service and stop it, the disk activity drops to normal. DisplayFusion is still eating CPU, but the disk churn stops.

Thanks, that's interesting! We'll check into the code to see what functions would be calling SeCreateGlobalPrivilege and see what we can find out.

Shutdown DF and ran as administrator, and the CPU pegging stopped, but the disk churn continued
For some reason, while DF is running, my Sound Driver application (not the driver itself) starts churning out SeCreateGlobalPrivilege requests and failing.
So, here is how everything stands

Everything works normally without DF
With DF, CPU pegs, DF hammers the event logs
With DF running as Admin, My sound application hammers the event logs
With DF running as Admin and the sound card application not running, everything is good

RealTek HD Audio Driver v 6.0.1.5988

Apr 1, 2015 • #22

Wow, that's really strange! If you disable the application hooks (Settings > Advanced Settings) and then restart DisplayFusion, does that make any difference?

Apr 1, 2015 • #23

Also, we've just posted 7.2 Beta 4. Could you give it a try, and if you still have this issue, attach a new debug log?

Thanks!

Sorry to take so long getting back.

Issue has not returned since getting rid of the sound card application, which I never used anyway, so I'm satisfied, but if you want to RCA it, I'm willing to provide logs in case there is a bug.

Jun 12, 2015 • #25

Ok, interesting! Was it just the audio driver, or the the Realtek helper app that seemed to be causing it?
