Black screens after resuming from sleep/suspend until hitting keyboard

I'm facing exactly the same issue after migrating from X11 to Wayland a few
days ago.

I usually leave my laptop's lid closed and use external displays only at my
desk (i.e. clamshell mode). The steps to reproduce this issue from me are very
similar:

1. Sleep (suspend to RAM)
2. Wake up the laptop using either keyboard or Wake-on-LAN
3. All displays, including the laptop's internal one, stay black
4. Hit any key on the keyboard, external displays will lit up

My environment:
Operating System: Arch Linux 
KDE Plasma Version: 6.5.5
KDE Frameworks Version: 6.22.0
Qt Version: 6.10.1
Kernel Version: 6.18.7-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 20 × 12th Gen Intel® Core™ i9-12900H
Memory: 64 GiB of RAM (62.5 GiB usable)
Graphics Processor 1: Intel® Iris® Xe Graphics
Graphics Processor 2: NVIDIA GeForce RTX 3080 Ti Laptop GPU
Manufacturer: LENOVO
Product Name: 21DECTO1WW
System Version: ThinkPad X1 Extreme Gen 5

Drivers:
iGPU: i915
NVIDIA: nvidia-open-dkms 590.48.01-2
Two displays connected via HDMI and USB-C (DP Alt) each.

Here's my `journalctl -b` output with irrelevant lines removed. I also enabled
Full Debug logs & restarted Powerdevil beforehand. I opened my laptop's lid to
reach the internal keyboard this time, so that the 'Lid opened / closed' logs
could serve as dividers.

One thing I noticed was that kwin spammed a lot of "Key repeat discarded,
Wayland compositor doesn't seem to be processing events fast enough!" when the
screens were black, and stopped after the screens are back.

BTW Bug 511811 might be the same?
