SUMMARY & STEPS TO REPRODUCE

Dual monitor: Left FullHD@100%, Right 4k@200% primary
Systemsettings -> Cursor -> Change size to any value

OBSERVED RESULT
The cursor size on the primary monitor does not change. It's always a fixed size.
It appears huge all over the screen, except for the Firefox window, where it is displayed smaller, namely like size 24 on the secondary screen.

The cursor size on the secondary screen however, changes according to the Systemsettings.

Looks okay on my machine with cursor size 24 and somewhat similar output setup.
Comment 2 postix 2022-02-14 13:40:39 UTC 
On the primary monitor, the cursor shows the correct size when hovered of the titlebar of a window, though.

Weird. Any idea, how I could debug this further?
Comment 3 postix 2022-02-14 13:49:24 UTC 
After playing around, swapping the primary screen roles, changing the scalings to 100%, 150%, 200%, etc. I now find that the cursor size never changes for any of the screens, except for the titlebar and the Firefox window.
Comment 4 postix 2022-02-14 13:52:22 UTC 
Replace Firefox with any GTK window in the comments above.

Did you reboot computer after changing cursor settings?

> Did you reboot computer after changing cursor settings?

That's a good point and led me to make the following interesting observation:

1) Initial setup before the reboot:
- Cursor size set to 24 in the KCM,
- visual appearance: 48 in general,  24 for the titlebars and GTK windows

2) Rebooted and logged back in:
- visual appearance: 24 in general and for the titlebars and GTK windows

3) Changed the size to 48:
- visual appearance: 24 in general and 48 for the titlebars and GTK windows

I also verified that the cursor changes but just logging back in. So either a reboot or a re-login is required on my side.

Okay, this sounds like bug 420859
