SUMMARY I've found a big issue with the Wayland fractional scaling, in which when you hover over the plasma desktop or taskbar the cursor becomes humongous (about 3x larger), this is despite what you set in the cursor size setting. Dolphin as well is affected, however Firefox in Xwayland, and other applications running with X seem to not be affected, nor is Kwin's window controls. I have been using Xrandr fractional scaling without such an issue. STEPS TO REPRODUCE 1. Set system scale (1080p 14in @ 1.2 scale) 2. Hover over the panel or desktop, dolphin, or other applications which use Wayland such as system settings or discover (I assume all Wayland applications are affected). 3: Notice the cursor inflates to a giant size 5: Hover over firefox, spotify, discord, or kwin's titlebar and note that the cursor appears to shrink back to a normal size. 6: The cursor looks fine in a screenshot even if it's a screenshot of the big or small rendered one. OBSERVED RESULT Cursor becomes huge and seems about 3x larger, making it quite unwieldy EXPECTED RESULT Cursor stays the same no matter what you hover over, at the correct scale.

Confirmed. I have a giant cursor in the desktop and other plasma windows even with the scaling factor set to 1.0. xdpyinfo says: ... dimensions: 3440x1440 pixels (820x350 millimeters) resolution: 107x105 dots per inch I don't know the equivalent way to get DPI in Wayland.

This behavior is caused by a different bug i think.
(To clarify: Change the cursor size from auto to a set size such as 24) ... I say i think it's a different bug because when i use 1.2 fractional scale (didn't test other scales), even changing it from auto to a set size the bug will persist.
Hmm, looks like dolphin, desktop shell, and other clients provide huge cursor surfaces.
I'm also seeing this, but I'm not running the Wayland session (as far as I know?). SDDM says "Desktop Session: Plasma", and has no other options apart from Openbox. This is with openSUSE Leap 15.1 and all the updated KF5 / KDE / Qt / Plasma repos. Currently at Plasma 5.16.5, KF5 5.61.0, Qt 5.13.1.

Currently at Plasma 5.16.5, KF5 5.61.0, Qt 5.13.1. Open the kicker menu and search "Wayland". You should see a application with that name and the description "Information about the Wayland compositor". If when you open that application it is populated with information, then you are on a Wayland session.
