After updating to version 10.0 through Steam, I've noticed that apps appear to be in front of the Displayfusion task bar. I have it set to the top edge, with autohide on, and when I have any window full screened, I can not bring up the bar. Even non maximized windows will cover up parts of the bar if they are in the way and even my desktop widgets will cover it up.
At first, I thought this was only happening with Firefox, but after more extensive testing, including several reboots, it appears to be happening with everything, even things like File Explorer Windows
I also use OpenShell, but it seems unlikely that the issue would be related there, and I haven't changed anything with OpenShell for a while now.
Edit: I'm not sure how I didn't notice before, but the same thing seems to be happening on my primary window where I use the normal Windows task bar. Maybe this is more of a Windows problem and not actually a bug in DisplayFusion.
Edit2: I seem to have fixed the issue with the normal Windows task bar by moving it to a different edge of the screen and back again, but even after a reboot, the issue persists on the DisplayFusion taskbar on my second monitor. If I disable the DisplayFusion taskbar and use Window's built in multi monitor taskbar, it works as expected, but turning the DisplayFusion one back on again still results in other windows displaying over top of it. If anyone has any thoughts, I'm out of ideas.
Edit3: Looks like my issue is a known one. See Win10 + DF10b2: auto-hide taskbars are under windows (not on top). Non-autohide taskbars are ok.

It's constantly happening, so this log was only active for less than a minute. I had a Firefox window maximized on my primary monitor when this occurred, but it isn't limited only to Firefox, as every other window I maximized exhibited the same issues, including Chrome, a File Explorer window, the Battle.net launcher, and Plex Media Player.

The same issue happens with DisplayFusion version 10.1-Beta3 as described previously. All other windows appear on top of the DisplayFusion extra task bar, from File Explorer windows to Firefox to Discord and anything else I tested with. It did not matter if the window or application as in full screen or not, and this still occurs immediately after rebooting the computer.

This behavior is not happening on the normal Windows task bar on the primary monitor, only on the Display Fusion second task bar.

I am running OpenShell.

This behavior generally does not happen (or happens very rarely if at all) on the 9.9 versions of DisplayFusion.
