Context
This issue started with a full system upgrade (sudo pacman -Syu) around 2 months ago.
I’m on a laptop running Manjaro with KDE 5.27.8 (Wayland) on kernel 6.6 (complete system info below).
Problem
My external monitor, which is can go at 144Hz, seems to be capped at 60Hz by something.
The built-in laptop monitor, a 144Hz panel as well, is working just fine.
Looking at KDE’s display settings, both screens are set to 144Hz. However, I cannot change the built-in one to 60Hz, it always works at 144Hz, for some reason (the setting seems to stick, but if I reopen the page, it reverts back to 144Hz). Changing the external monitor’s refresh rate “works” (as in, the setting sticks), though it changes nothing.
I’ve tried using kscreen-doctor to change settings, to no avail either.
Here’s what kscreen-doctor -io gives me:

Has anyone had anything similar? Could it be some regression to the Intel graphics driver (the HDMI port is driven by the iGPU, not dGPU)? Is it a KDE bug?
Thank you!
