Changing display resolution via kscreen-doctor under wayland fails

I am unable to change the display resolution on my KDE Plasma installation via System Settings nor kscreen-doctor.

As you can see occassionaly core dumps occur:

> kscreen-doctor -o
Output: 1 eDP-1 enabled connected priority 1 Panel Modes: 0:2880x1800@90*! 1:1600x1200@60 2:1280x1024@60 3:1024x768@60 4:2560x1600@60 5:1920x1200@60 6:1280x800@60 7:2880x1620@60 8:2560x1440@60 9:1920x1080@60 10:1600x900@60 11:1368x768@60 12:1280x720@60 Geometry: 0,0 1440x900 Scale: 2 Rotation: 1 Overscan: 0 Vrr: incapable RgbRange: Automatic
malloc_consolidate(): unaligned fastbin chunk detected
[1]    12907 IOT instruction (core dumped)  kscreen-doctor -o

Setting a different mode seems to work, however QSize in the returned Config remains the original 2880x1800.

>  kscreen-doctor output.eDP-1.mode.5
kscreen.doctor: Taddaaa! Found mode "5" "1920x1200@60"
kscreen.doctor: Output 1 set mode "5"
kscreen.doctor: setop exec returned KScreen::Config( 
KScreen::Output(1, "eDP-1", connected enabled priority 1, pos: QPoint(0,0), res: QSize(2880, 1800), modeId: "5", scale: 2, clone: no, rotation: KScreen::Output::None, followPreferredMode: false) )

Here is my neofetch

----------- 
OS: Arch Linux x86_64

Kernel: 6.2.11-arch1-1 
Uptime: 35 mins 
Packages: 1621 (pacman)

Resolution: 2880x1800 
DE: Plasma 5.27.4

Terminal: konsole 
Terminal Font: Hack 14

GPU: NVIDIA GeForce RTX 3050 Ti Mobile

And my graphics driver:

glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Mesa Intel(R) Graphics (ADL GT2)

At the same time, changing the display resolution works under Gnome 43.

Any ideas what could possible be wrong here?
