Odd notification widget behavior with multi-monitor

Help
1

So months ago switching from plasma5 to 6, I moved from using latte-dock to native plasma panels across my 3x displays, and added notification widget to the 3rd display top panel, which tends to be where I look at/work most of the time, and for a time, it was good. Since there’s no “copy/duplicate panel between monitors” option that’s been talked about, most of my widget additions ended up on the 3rd monitor including notification.

A few months later, something glitched with plasma that jumbled the panels around displays (a whole other issue), and the panels from the 3rd display somehow relocated to the first monitor, and the other two more basic panels ended up 2nd/3rd display. Annoyed, I mostly duplicated my widgets between the 2nd and 3rd monitors manually now, including notification, and mostly works as intended…

The problem is more notifications now only show on the 1st monitor vs. on either of 2nd or 3rd instead or as well. Adding the notification widget to monitors 2 and 3 panels, I only see them on monitor 1 still, which is a 15" laptop to the side of 2x 50" TV’s I normally use as displays to the side, so needless to say I never see or notice notifications now.

Attempting to remove the notification widget from 1 and trying to force them over to either monitor 2 or 3 that I’d be happy with, it simply will not let me, in that if I remove it from the panel, it does, but immediately shows up there again, like it simply will NOT let me remove it.

I’m fairly certain this is unintended behavior, but what should be the expected behavior for notifications? Notifications have always been quirky even under plasma5, that I can’t get notifications on multiple displays, and would always oddly track the “primary” display usually, but being highly unstable which plasma would actually keep using as primary, was never very deterministic, but this is now weird and different.

I’d love to simply get notifications on either/both display 2 or 3, never 1 unless the only display being built-in on the laptop. Any thoughts on the best way to accomplish getting notifications visible on specific displays or at least all of them definitively?

This has been an ongoing problem for me since P6. IMO Kwin or some other component in Plasma is rather broken, as there are a lot of odd behaviors that relate to multi-monitor setups. I recently “downgraded” my rig from 2 dedicated GPUS driving between 5 and 6 monitors, to one GPU driving only two to try to get it to play nice, and that has mostly succeeded, but I do miss the added 3D Cuda rendering ability in Blender, and I do miss the extra real estate on my desktop.

I do like the added game and desktop performance as piping through a second GPU does come with an overhead penalty, but I would prefer it work the way it has for the past few years under Plasma 5.

well, I’m struggling with the position of the notification popup, too…
I’m using Plasma 6.1 with Wayland…
It’s normally shows the notification on the left monitor, that’s fine… But, many times, after a resume… the notification popup is being shown on position (0,0) on the top-left corner, regardless of the notification popup position settings…
The other issue is that when I plug out the 2nd monitor, some windows remain “off-screen”… and sometimes it’s hard to move them on the laptop monitor… (the standard window’s “Move” with a hotkey used to work, but it’s not anymore). (These windows in many times are shown from a container, shared DISPLAY/WAYLAND_DISPLAY variable).

I’m writing this 2nd issue, because it could be related…
