plymouth debug log during boot

Description of problem:

Plymouth visual stall during boot and LUKS passphrase entry.

Version-Release number of selected component (if applicable):

My system is a Ryzen AI 9 HX 370 CPU providing integrated graphics, and an Nvidia RTX 5070 Ti, an asus zephyrus g14 laptop.

How reproducible:

Always on my setup.

Steps to Reproduce:
1. Boot the computer
2.
3.

Actual results:

The luks passpharse entry screen is shown, but no keypresses are echoed, but if I enter the password blindly, the boot continues. The screen refreshes only at the GDM login screen.

Expected results:

The keypresses are echoed back to the screen.

Additional info:

First I suspected some timing issue between the dGPU and the iGPU, and tried to disable the dGPU entirely using udev blacklisting, but the bug stayed.
