Auto-Hide OPUS toolbar completely hidden in Windows 10

I have an Opus toolbar (titled "desktop") that spans my monitor width (at the bottom of the screen, horizontally) which I have set to auto hide... very often throughout the day it REFUSES to display when I point the mouse to the area where it resides [usually out of sight]. The only way (in Windows 10) I've found to get it back is to right-click the Opus icon in the tray, hit "customize," point to/reveal the [hidden, auto-hide Opus toolbar] then click ok. But after a while (minutes or hours) the same crap will happen again & I'll have to do the same thing to un-hide it. VERY annoying problem -- any solutions to make it permanently STICK? Thanks!

Try setting it to On Top > Always via the right click menu.

If that doesn't help, how many monitors do you have and, if more than one, are they mixed DPI?

The toolbar is/has been set to always on top. I have 2 monitors; they both have different DPI settings.

There are some serious bugs in Windows 10 and the way it positions docked AppBars (which is what the toolbar is) under mixed DPI, unfortunately.

e.g. The taskbar position on one monitor can affect the area given to an appbar on another monitor. Switch both to the same DPI as each other and the problem goes away.

e.g. For me, if I have 200% DPI 3840x2160 on the left, with the taskbar at the bottom, and then dock an AppBar to another monitor 100% DPI 1920x1080 on the right, the AppBar is sized to one pixel high, and appears offset from the bottom of the screen by both the real height of itself (good) and the height of the taskbar on the other monitor (bad). If I move the taskbar around the other monitor, the AppBar can become visible again, but still has incorrect size or position if the taskbar is on the bottom or right of the other monitor, or on the bottom of the monitor the appbar is on (where the appbar will then be placed overlapping the taskbar).

You may find things better if you move either the toolbar or the taskbar to the left or top of their respective screens. So far I haven't noticed any Windows 10 bugs with that configuration.

In summary, AppBars are broken in Windows 10 when using mixed DPI screens. (Lots of other things are as well, I've been noticing. It can't even draw window borders properly. Clearly Microsoft have not put much testing into this scenario, unfortunately.)

Just had a chance to check -- monitor # 2 is only capable of 1600 x 900 resolution, while monitor # 1 is at 1920 x 1080 -- they're both scaled at 100%. Thanks for the feedback... one can only hope these issues will be resolved in a future Windows update.

Interesting, perhaps the issue is with mixed resolution monitors rather than mixed DPI. The recent testing I've been doing with mixed DPI has also meant I'm using mixed resolution, so I may have misattributed the cause there.

Agreed, I definitely hope Windows updates fix some of these things as I have found a lot of bugs in Windows while doing DPI work lately. I was expecting problems from applications but I found some shocking bugs in the OS itself. It's a bit worrying that Microsoft still haven't got this right.

I just went into Opus Preferences/Launching Opus/Default Lister & changed "default lister positioning" from "in a fixed position relative to the monitor the mouse is on" to "always in the same positioning." Will let you know if that helps curb the behavior.

Yes that relates to listers/not toolbars but it's the only thing I could find in the settings that mentioned a monitor.

only thing I could find in Opus preferences

Fixed -- don't know which of these 2 tweaks worked but the problem is fixed -- I changed the taskbar icon size from small to large & also set the taskbar to display only on monitor 1
