screenshot of blurry "unread notifications" icon

On my 4k 27'' monitor with 200% scaling, I always get a blurry icon in the notification plasmoid when I have unread notifications. See attached screenshot.

The other icons in the notifications plasmoid looks all good (e.g. the one when you enable the "Do Not Disturb" mode), so I believe the "unread notifications" icon is the only one affected by this issue.

How odd. Never seen this myself with ma 4k screen with 200% scaling.

Are you using Wayland or X11?

Wayland. I also forgot to mention that I have a dual-monitor setup, the 2nd monitor has fullhd resolution and 100% scaling.

Facing the same issues here. I'm on a dual monitor setup, one with 4k screen and 200% scaling, and the other a 1080p screen with 100% scaling. Several icons are blurry, some icons (like bluetooth) have a thin line compared to the rest. I'm running the system on Wayland, with FOSS AMD drivers.
Comment 10 postix 2023-04-10 15:39:05 UTC
In your setup, how are the screens positioned? Which one is the primary and which one is one the left or right?
I have all kinds of issues with a mixed dpi setup using 2k@100% on the left and 4k@200% on the right, which is the primary.
Comment 11 Nate Graham 2023-05-07 16:21:28 UTC
I can confirm that this is fixed in a Plasma 6 Wayland session!
