Public bug reported:

OS: Kubuntu 26.04 development release.

Steps to reproduce:

1. Find a machine (like a KFocus NX GEN 3) where the EFI framebuffer driver is 
not able to support the full display resolution of the machine.
2. Install Kubuntu 26.04 on that machine with disk encryption enabled.
3. Reboot, see distorted disk decryption screen.

This is hardware-specific - some machines like the XE GEN 1 have a
decryption screen that works perfectly fine without an advanced driver
like the i915 driver, but other machines need a dedicated graphics
driver for the display to work right. initramfs-tools seemingly used to
be able to find and embed such a graphics driver, but now no longer
does, and even has taken steps to prevent the embedding of a full driver
(like https://salsa.debian.org/kernel-team/initramfs-
tools/-/commit/8aec85230b7ee0a1cca807c97d7dc1f3abbdf3a5).

This can be worked around by adding graphics drivers to /etc/initramfs-
tools/modules, but preferably there would be some option in initramfs-
tools that could be set by default to detect and include full graphics
drivers for the system's GPU.

** Affects: initramfs-tools (Ubuntu)
