Incorrect resolution/scaling after update from version 22 to 24

I'm on Arch Linux (KDE) and updated Plymouth to version 24. Then, upon login, the Plymouth password screen appeared to be in a much lower resolution than my native resolution. However, when I checked on my monitor (using OSD) it said '3440x1440' - which is my native resolution. So it appears the screen was rendered at a lower resolution (1920x1080?) and then zoomed to my native resolution, thus appearing blurry.

I turned on Plymouth debugging (complete, relevant part of the log) and I noticed this:

../plymouth-24.004.60/src/libply/ply-utils.c:549:ply_open_modu: Could not load module "/usr/lib/plymouth/label-pango.so": /usr/lib/plymouth/label-pango.so: cannot open shared object file: No such file or directory

But then I checked and the file was clearly there. So a bit puzzling why it was complaining about the file. Also, this error might not be the cause, but I couldn't see any other issue/problem occurring.

Upon downgrading Plymouth from version 24 to 22 (24.004.60 to 22.02.122, to be precise), the problem was gone and the screen rendered just fine.
