System:
OS: Debian GNU/Linux 12 (bookworm) x86_64
Host: 20U9006BUK ThinkPad X1 Carbon Gen 8
Kernel: 6.1.0-10-amd64
DE: GNOME 43.4
CPU: Intel i7-10510U (8) @ 4.900GHz
GPU: Intel CometLake-U GT2 [UHD Graphics]
Display Server: Wayland
My laptop screen resolution is 3840x2160 and it's set to scale 200%. My external monitor resolution is 2560x1440 and it's set to scale 100%. This generally works fine connected via HDMI but whenever the laptop goes to sleep and is woken up the monitor resolution gets set to 1920x1080 until the HDMI cable is unplugged and reconnected (at which point the correct resolution is detected again).

Anybody know how I can fix this and/or if a bug report already exists or where I should submit one if not?
