High CPU usage / freeze after period of idle time

Been having problems with DF ever since updating to v4.0. CPU usage for DisplayFusion.exe frequently and seemingly randomly jumps to around 15% (presumably 100% of one of the cores on my hexacore CPU). Often, but not always, that corresponds with DF becoming extremely slow to respond to mouse clicks, and sometimes it becomes completely unresponsive and can only be fixed by killing the process and restarting DF.

I only use DF's multimonitor taskbar functionality. Titlebar buttons, screensaver, desktop wallpapers, etc. are all disabled.

I've searched the forums but the only similar reports I see are related to using other software (Bins, EA Origin, etc.), none of which I'm using.

The only other unusual thing I've done lately is to add another monitor to this system via a USB video adapter (EVGA UV+19)... I can't think of any reason why DF would have problems with that though...?

I can submit a troubleshooting log if needed, but I'd prefer to do it privately as this is a business system. I haven't tried the latest DF beta either for similar reasons -- it's a production development system and I use DF heavily so I'm hesitant to risk making things worse.

Does it seem to spike when the wallpapers are changing (assuming you have it set to randomly change)? If so, could you tell me approximately how many images you have in the folder that's selected for the wallpapers?

Thanks!

Erm... no. From my original message:

I suspect this other issue report may be related, btw:

Ok, so it seems to be creeping up over time, as opposed to spiking and dropping?

I believe it occurs fairly abruptly.. usually I first notice it when my secondary monitors' taskbars suddenly become nearly or completely unresponsive, and/or when I hear my CPU fan suddenly rev up to cool down the processor.

And yes, once the problem starts, the DF process continually fluctuates between roughly 7% - 15% CPU utilization, and never drops back down.

Ok interesting! Would you be able to do the steps in the following post, and just reply there? That way we can keep all of the information together
