My Display Fusion is definitely having memory issues!
It's constantly increasing memory usage at an alarming rate. In task manager I can watch the working set and commit size steadily increase, at the moment 760k working and 1.2GB commit, and rising. GEEZ!
log attached.
Please advise ASAP!
Thanks,
Ken

Yeah, I installed the BitDefender trial about an hour ago, and I can already see DisplayFusion's memory usage increasing since then. I'm going to let it run over night, to confirm.
My initial investigation seems to point to the "Active Virus Control" heuristic part of BitDefender, which can actually be disabled separately from the normal On-access scanning. The Active Virus Control seems to be hooking DisplayFusion and loading in a DLL (avcuf64.dll) to the DisplayFusion.exe process, which is likely what's causing DisplayFusion.exe to leak memory.
At any rate, I'll follow-up again tomorrow after it's had a chance to run longer, and I'll also try disabling the Active Virus Control in the morning to confirm that that is indeed what's causing the issue.

I've also encountered this memory leak issue and am running BitDefender - at one point the Display Fusion process was using > 2GB working memory.
I've added the Display Fusion Program Files folder / *.exe to the excluded list for the active virus control scanner in BitDefender. Hopefully that will fix things.
Are there any additional DF files outside of the DF Program Files folder I need to add to the exclusions listl?
Nope! All of the executables are in that directory. Make sure to reboot after adding the exception, as BitDefender may not unload the hooks until a restart.
@David: Quick question: I've only been able to find a way to add exclusions for on-access/on-demand scanning, and not for the Active Virus Control heuristic scanner. Is there a different location in the settings for that?

Can confirm that adding the Display Fusion Program Files folder / *.exe to the excluded list for the active virus control scanner in BitDefender appears to fix the memory leak problem.
After almost 30 hours up time, the DisplayFusion.exe process is still only using <100MB of memory, similar to my long term historical observations.
Yep, same here as well. Thanks for posting that solution David!
