It is probable easier to copy and paste that here :) What I wrote there is:

I think the PSR triggered plymouth problem is a kernel driver issue. Plymouth
re-uses a single framebuffer, calling drmModeDirtyFB() on each update, I think
that the driver does not properly recognize / tracks that a call to
drmModeDirtyFB() means the panel needs to be taken out of self-refresh as there
is new contents in the framebuffer.

This at least goes for the password screen is shown, but no keypresses are
shown case. If nothing is shown at all that might actually be a plymouth issue,
I hope to create a patch for what I think is the cause of that next week and I
will ask for testing that patch in
https://bugzilla.redhat.com/show_bug.cgi?id=1490490.
