I'm experiencing a bizarre issue with the taskbar notification area in Windows 10 1909. I only just noticed this issue but I have no idea how long it's been happening since I didn't pay too much attention to the notification area before.
If I only enable a single icon in the notification area then everything is fine, the one icon is displayed in the notification area. But if I enable two or more icons, then all the icons are displayed except for the first one, which is replaced by an empty space.
Here's what it looks like:
I actually have three icons enabled, but there's an empty space where the first one should be, between the two icons and the input method selector (the ENG DV thing).
I experience this issue regardless of which icons I choose; as long as I've enabled more than one, the first one I enable is hidden, while the others are correctly displayed. The same is true even if I put the taskbar on the right or left side of the screen, so that it's verti
I have tried deleting the "IconStreams" and "PasticonsStream" keys in \HKEY_CURRENT_USER\SOFTWARE\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify, which I've seen suggested in a number of places, but this had no effect.
I haven't been able to find any mention of this issue on the internet, let alone a solution, so I'd greatly appreciate any help here.
EDIT: another thing I noticed, in case it helps diagnose the problem: if, when dragging a new icon onto the notification area, my mouse cursor is on the blank space when I let go of the mouse button, I see this weird UI element in the space where the first icon should be:
As soon as the mouse leaves that space it goes away and goes back to being an empty space.
