The 'Details' Boot Splash Screen, which I assume is supposed to show the verbose text-based boot screen where the status of various services being started is displayed, doesn't work half the time. Sometimes on shutdown I do get the details of services being stopped, but on boot I've never got that - it just shows my laptop's vendor logo the entire time and no text at all.
STEPS TO REPRODUCE
1. System Settings: Startup and Shutdown -> Boot Splash Screen, select 'Details'
On boot, only the laptop vendor logo is shown. On shutdown, sometimes the details screen *is* shown, but most of the time the screen is just blank during shutdown.
The text logs of the starting/stopping of the services and stuff should be shown
Operating System: KDE neon 5.22
KDE Plasma Version: 5.22.5
KDE Frameworks Version: 5.85.0
Qt Version: 5.15.3
Kernel Version: 5.11.0-34-generic (64-bit)
Graphics Platform: X11
When alt-tabbing into the details screen when Breeze or something else is enabled, it works properly all the time.
This is a plymouth splash screen and not the Plasma splash screen. It's also not provided by KDE code; please report upstream. Thanks!
