Hey,

I was evaluating DF the last week and just today it started using 100% CPU.
It's still "working", so the process is still responsive in a way, very slow, but it's there.
In Process Explorer I can see the memory usage going up and up, way over a Gigabyte and then dropping again, this loops forever.

As I said. It was running well over the last week.
I'm on Win7 64 Ultimate.

reinstalling didn't help btw

Odd. Does going back to an older version help at all? I believe the DLs are around here somewhere. Are you using any other theme or window changing software?

I too have been seeing a 100% CPU Utilization. I only encounter this though when I close my laptop while connected with an external monitor. This puts my laptop to sleep and when I bring my laptop back up when I get home without the second monitor I see the issue. This does not happen every time but it does happen quite often. When I finally get to task manager/Process explorer the culprit is the DisplayFuson.exe. I have been able to kill the process and the system return to normal but yesterday the CPU dropped to 50%. Looking in Process Explorer I saw DPCs (Delayed Procedure Calls) consuming the CPU.

I have noticed this with v3.1.7 also. Here are my specs:

HP 8510W
4GB Ram
Windows 7 RTM x64
ATI Mobility FireGL v5600 (Driver 8.632.1.3000)

I am still using the default Windows 7 Background so nothing fancy there but I do use the title bar buttons. I have not done any troubleshooting yet such as disabling the title bar buttons. I will try that tonight.

I typically move all of my applications back to my Laptop screen prior to putting it to sleep but I keep the Second Task bar loaded. I would be more than happy to get a memory dump if needed or any other trubleshooting steps if you all need.

Thank you,

Marco

Will do.

My machine pretty much becomes unresponsive. I can do things but it is very slow. The mouse becomse choppy and cumbersome to navigate any thing within the GUI.

Before my initital post I uninstalled DF, reinstalled it now and it's not happening.
I will notify you once it happens again.

But as I said, when it happened, DF was still there, but very slow, I could click around in the menus, but with a delay of something like 3-5 seconds.

Screenshot and log file sent to your E-mail.

Thanks for your time Jon!

ps. Sorry I spelled your name John in teh e-mail.

That is correct. When I plugged the machine into AC power the problem went away.

Just a side note, no problem with CPU load on my Win7 x64 system (but then again it is a desktop).

Jon,

Interestingly enough the problem still exists but I have discovered another odd twist. As mentioned in one of my previous posts the problem goes away when I plug the laptop into AC power. Last night I plugged in AC power so I could get control of the machine and exited DisplayFusion but when I unplugged the AC and went back to battery I immediately experienced the problem again. I am not sure if the problem occurs and the stuck thread hangs around and doesnt really close even though I closed DF or if this is not really a Display Fusion problem at all. I think I may uninstall DF and see if I can reproduce it tonight. I can pretty much reproduce it at will. Hopefully removing DF will let me know where the problem lies. I will follow up with more information later tonight.

Thank you

Jon,

Okay I uninstalled DF prior to putting my machine to sleep tonight. I got home and had the issue so at this point I am leaning away from DF as the issue of my CPU. Looking in Process Explorer my CPU time is being consumed by DPCs so I am suspecting a faulty driver/power state issue. I am going to start digging in to this problem to see if I can resolve my issue. Again thank you for your time!
