I'm on Windows 11 and I've enabled displayfusion's taskbar to auto-hide. I move the mouse to unhide the taskbar then move it to an icon to reveal thumbanil previews. The problem occurs when I move the mouse up towards to any preview. The taskbar will sometimes auto-hide right away leaving me unable to select the thumbnail.

I suspect it's due to the desktop gap between the taskbar and the preview windows. When the mouse hovers over that area, it'll dismiss the taskbar. I've tried being fast, but sometimes it'll still auto-hide. When you compare it with Windows' taskbar, it gives ample time to slowly hover the mouse over - even several times. I've tried setting the 'Thumbnail Preview Close Delay' to 5000ms to no avail. Is there another setting to increase the delay to when the taskbar should autohide?

Please see the video for a demonstration.

Here's the file.

No, I don't see any. I've closed all my device controls such as logitech ghub and such.
The only remaining is windows itself - which the taskbar, I've set to not auto-hide on the main monitor, and not "Show my taskbar on all displays". If there's no solution then I'll just use window's taskbar. I liked pinning apps to the display's taskbar that I usually open them on

Thanks for troubleshooting.

If I could add to raceconditions post, I have noticed this issue also.
While having the taskbar set to auto-hide - when you hover the mouse near to the monitor edge - the taskbar 'appear'(rises from bottom edge) and 'disappear'(lowers to bottom edge) speed is VERY quick and 'jumpy.' It doesn't 'appear' in a slow and smooth manner - and if your mouse is just a touch off of being horizontally centered on the now-appearing taskbar - the taskbar will often 'disappear' again.
If the 'appear' speed was slower, the 'disappear' speed slower - it would be much easier to 'grab' the taskbar, to then use it.
