Created attachment 175351 [details] System Notification Settings SUMMARY Notifications sometimes show up for as long as they are supposed to and sometimes disappear after a fraction of a second. I have had this happen both with system notification events like plugging in a USB stick and also with Firefox notifications from Discord. Unfortunately I've been unable to find a pattern to it but my experience is almost exactly like this post on Reddit. https://www.reddit.com/r/kde/comments/1byzci9/help_needed_for_notifications_disappearing_too/ Like that poster, I am also on an up to date Arch system with an AMD GPU and a single 60 Hz monitor. Like that poster, it happened on both KDE5 where I was running XWindows and on KDE6 where I'm on Wayland). Like that poster, the kdialog test works fine. Some other info that might be relevant - All notifications appear properly when I click the Notifications icon in the System Tray - I've messed with the notification settings and that didn't help - I've had it happen when both typing and when just looking at the screen without even moving the mouse Screenshots of my notification settings are attached Operating System: Arch Linux KDE Plasma Version: 6.2.1 KDE Frameworks Version: 6.7.0 Qt Version: 6.8.0 Kernel Version: 6.11.5-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 1700 Eight-Core Processor Memory: 15.5 GiB of RAM Graphics Processor: AMD Radeon RX 560 Series

Correction: I said "All notifications appear properly when I click the Notifications icon in the System Tray" above. That's incorrect. In fact I've just had a bunch of Discord notifications flash by and the last notification from Firefox was 9 minutes ago. One flashed by just as I was typing this and while the Notifications window was pinned: the Discord notification from Firefox flashed up on top of the notification window but did not appear in the list of notifications.
Apps can revoke their own notifications, which can be a source of this. Discord does it when new messages arrive, to prevent excessive message notifications from appearing on the screen at once. You said it also happens for the notification "when plugging in a USB stick". To my knowledge there is no notification for this, at least not by default. Can you clarify? Maybe take a screenshot of it when it appears?

Perhaps, but I'm doubtful. I think every notification I get flashes up on the screen. So rather than them not all appearing at once, they all cause an annoying flash on my screen and all immediately disappear? That doesn't sound like it would be by design and it also doesn't explain the other issue I'm having with plugging in devices. I also have Discord set up to send very few notifications so a flood of them would be rare. But still, I often see a single message flash on my screen and then disappear too fast to read. On those few occassions where I get multiple notifications from Discord at once, I will usually see them both flash on the screen stacked up and then they'll both disappear. But again, this isn't consistent. Sometimes they are displayed for the proper duration. > You said it also happens for the notification "when plugging in a USB > stick".

The notifications come from the Disks & Devices icon in my System Tray. I'll add a shot of it plus the application settings for the Device Notifier in another attachment.

OK, so that's not a notification, that's a System Tray widget. It's not controlled by the notification settings. Any chance you could also take a screenshot of the other things that disappear quickly so we can see if those are really real system notifications, or something else?

I got onto a little busier Discord and asked for notifications for all messages and then hit Shift-R in Firefox to reload the page. I quickly got a stack of three notifications that were properly stacked and didn't instantly disappear. After a bit, this sole message in "ShortNotification.jpg" popped up and disappeared very quickly.

OK, those are definitely normal system notifications. Thanks. BTW, nice choice in 3D printers. :) I almost went with a Voron V0 earlier this year, and a Prusa Mk4 only very narrowly beat it out.
Thanks for the compliment. I like my Trident a lot :-) Is there anything further I can provide or something I could try to help debug this? I'd love to get to the bottom of it.
Unfortunately I'm running out of ideas. Does the issue reproduce in a new clean user account?

Good suggestion. I'll give it a try but my time is a bit short right now. I'll get to it when I have a chance.
