Hi Gert,

thanks for the feedback.

Would you mind confirming which theme you’re using ?
So far I fixed it only for the Homeworld theme, the default for Bullseye.
If not your current theme would you mind trying with it and reporting back ?

When I say fixed, I didn’t try with your exact resolutions but I now have a 
laptop + external monitor, and I definitely experienced the bug as you 
described it and made a change that fixed it.

The fix is at /usr/share/plymouth/themes/homeworld/homeworld.script:122

-    min_height = Window.GetHeight();
+    min_height = window_max.height;

You may want to try that with other themes and also report back if you feel 
like it.
You can directly change the script in
    /usr/share/plymouth/theme/$theme/$theme.script
and remember to update-initramfs -u before rebooting to test the change.


Happy hacking !
