I'm Running Windows 10 Insider Preview 17025 with DispalyFusion Pro on Steam 9.1
I have a 3 monitor setup, with the center monitor as primary.

Displayfusion is managing the TaskBar, as you can see in the clip I linked below the TaskBars on monitors 1 and 3 blink in and out. I've done a search, but haven't found a way to solve this. Any Ideas? (I've also linked my Log File)

Having the same issue.
This log occurred when it happened. lines 44-45 show taskbar 2 closing, cant seem to figure out why though...
I'm pretty sure I would have noticed if it did this in the previous version, but I'm a pretty new user of DF.

I tried it again after playing with some Windows settings, but still no go.
Same issue, the DisplayFusion Taskbar keeps blinking.

Attached are new Debug files.

Tried that, even from a clean boot with everything else diabled the problem still occurs.

I did as suggested.
I used MSConfig, under General tab, I selected Diagnostic Startup, so only basic devices were loaded. The DisplayFusion TaskBar worked normally. So seems to me that I have a program/driver conflicting.

I restarted Windows normally, the TaskBary started to blink again. I closed all background applications one by one to try and isolate the offending program, but no luck.

Any ideas on how to troubleshoot this further?

Great minds think alike!
Last night I was tinkering around and decided to completely uninstall Spacedesk, wasn't using it too much anyways, the Taskbar issue seems to be fixed.

The first time I just stopped the program, I didn't disable the service, I think that's why I was still getting the blinking. Now with the program fully removed, no issues, so far.

I'll use the DisplayFusion Taskbar for the rest of the day, to see if I get the blinking again. I'll post an update later today.

I was similarly able to fix the issue by preventing a dll from loading. For me it was VdmInj64.dll from Virtual Display Manager and preventing the service from starting at boot wasn't enough.

The issue I have now though is that the one feature I hoped you guys had(and the primary reason for my purchase) is the ability to have youtube or similar sites maximized inside of a virtual monitor. VDM allows that. Any chance there is a plan or roadmap to getting this feature added?

I've included logs and the troubleshooting info from after I re-enabled the dll.

Interestingly, with splits and padding disabled in DF, multi-monitor taskbars work for the two physical monitors, but do not respect the 4 sub-monitors I have defined in VDM.

Got the two working peacefully now. Had to check off the shrink taskbar option in VDM. Thanks for the help resolving the issue.

I'm having this same issue. I don't have SpaceDesk or VDM running. Any idea how to stop it?

I am using 3 monitors and the task bar still blinks. I have done a minimal logging and attached the log file. It happened on 10:09:09 and 10:10:24.
From the log file, it looks like iTunes is the cause as I have put iTunes in compatibility mode so that I can play movies full screen, but I am not 100% sure it is the only reason. Quitting iTunes seems to help.

Even if iTunes is the cause, how can I fix this as iTunes is a key program for me? I did not run iTunes in the second nor third monitor where the task bar blinks is happening.

Currently using 12.10.7.3.
I think this is a 64-bit version.
