Previously this year, after a windows update, some tray icons were missing from the multi-monitar taskbar. Eventually, the issue resolved itself, I assumed via an update to either Display Fusion or Windows.
(I have my taskbar set to display all the tray icons on both monitors)
However, since last week, this issue returned with the most recent windows update.

Is this a known issue? If needed I can dig in and get my windows/DF versions and provide logfiles.

Here is the file! I thought maybe it was related to the number of items, rather than the specifics, but changing them around results in the same behavior (same icons hidden), if that helps at all as well.

Hey Owen, I just tried that this evening, but it did not seem to fix the issue. I've attached logs from using the Beta version if that might help out.

Hey Owen, sorry for a late reply on this - I've been away from my PC.

I spent some time going through my PC to see what could be contending with this, and I was able to fix it.

What ended up happening was some contention with a tool I use called "ExplorerPatcher". The tool was outdated and Microsoft Defender was blocking an update. Once I updated that to the latest version, the issue was corrected upon a system reboot.

I am very sorry to waste the dev time looking into this when the issue was external. Is there anything I can provide for more known issue tracking for this software comptability that may be useful?
