[Bug] Notifications stop working after some time - repeat

[onyx-tty]

Describe the bug
Reopening of issue 682. swaync at some point stops displaying notifications.

Expected behavior
Notifications display correctly even after hours of usage.

Please provide logs if you're experiencing notification errors / bugs

Desktop (please complete the following information):

• OS: Arch Linux
• Version: 6.18.7.zen1-1

Additional context
The problem has been recurring even after weeks. I've been tracking the original issue hoping the problem will be fixed when the other issue is closed, but it didn't.

Happens on both extra/swaync 0.12.4-1 and the newest aur/swaync-git r670.5228963-1. Updates haven't solved anything.

Looking at the logs, each time a notification fails to send, the SWAY_NOTIFICATION_CENTER_CLOSED_REASONS_EXPIRED error is visible.

Thanks for the report! Are the latest notifications in the log the ones that aren't being displayed? In that case, it seems like it gets added and then expires after a few seconds (as it should do), but it's strange that it's not being displayed on screen...

Could you test running with GSK_RENDERER=opengl? The GTK4 vulkan renderer seems to be a bit buggy for some systems
