Before clearing the screen, ensure that no previous output of firmware or UEFI programs will be overwritten on serial devices or other streaming consoles. This helps generating complete boot logs.
Tested regarding multi-output against qemu-x86_defconfig.

Please see this thread...some things need to be improved in this area.

Is there a conclusion already? Is there something that I can attach to to resolve this issue here?
So far as I am concerned, there is a conclusion :) I provided a lot of detail in the thread linked above.
Simon, if you want to filter output on the sandbox you may do so in the serial driver of the sandbox. It is not related to the UEFI code.
From what I can tell this problem also affects the qemu CI tests. It
seems that UEFI needs ANSI so this appears to be a UEFI thing. I haven't actually noticed any other use of ANSI sequences in some years of using U-Boot.
