It's still an open bug and wouldn't be hard to fix by going back to the
old way: Just put all graphics drivers in the initrd if and when a
password prompt is required. But I am holding out for something better
that won't reintroduce ~90MB of bloat.

Assuming the graphics mode is correct for you when the bug occurs then
it could be fixed by just changing the heuristic in plymouth when the
physical monitor dimensions are unknown (because the full graphics
driver is absent). What is the diagonal size of the 2560x1440 screen in
this case?

Also I just remembered you should be able to work around it in theory by
adding PLYMOUTH_FORCE_SCALE=1 somewhere in the systemd scripts.

Title:
  [noble] Huge prompt for encrypted disk pwd

Status in plymouth package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  plymouth (24.004.60-1ubuntu6) noble

  I get a huge prompt asking my luks-encrypted disk, at early start-up.

  Seems to be linked to screen resolution as I experience this bug only
  on my 2560x1440 external screen, not the 1900x1200 one. Only 1 monitor
  is active in both cases.
