Re: [edk2] OVMF Logo
You shouldn't have to hack BGRT in OVMF since you change the logo in the EDK II source. Can you provide a screenshot to show what the logo corruption looks like?

Re: [edk2] OVMF Logo
I'm unclear what you mean by "overlap Windows Logo". Can you provide a
screenshot?

Hmmm, generally that shouldn't happen; the logo's location is made available to
windows via the BGRT (boot graphics resource table) ACPI table. When we added
BGRT support to OVMF [*], the location / appearance of the Windows boot
animation did change (because it started considering the TianoCore logo
displayed by OVMF), but I don't recall any actual
*conflict* between the logo & the boot animation.

In brief, this shouldn't happen, and if it does, it's not specific to OVMF --
can you perhaps provide more information so that the MdeModulePkg maintainers
might help with the investigation? What Windows release? What boot animation
exactly? What screen resolution?
Thanks!
