I think plymouth is trying to load the png without it being mounted yet? If you look at the debug log and search for loading lock image you will see that there's an error on the first load but there's another one where it's successful. The first is when booting, the second is when I press esc, so maybe at boot, /usr/share/plymouth/themes/spinner was still not mounted but on pressing esc it can find it already.
Thanks for looking into this. ** Attachment added: "plymouth-debug.log" https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/1838725/+attachment/5288865/+files/plymouth-debug.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838725 Title: Plymouth fails to display graphical splash screens on some machines, shows text mode dots animation instead.
