D796 - A presented frame is shown opaque

Status: decided Date: 2026-10-11

The GUI shows a frame the guest presented as opaque: each pixel's colour as the buffer holds it, its alpha ignored. A console scans its display buffer out to the screen and blends it with nothing, so the alpha a title leaves there never reaches the picture.

Why: PPSA28061 draws its game through a CRT filter that leaves alpha zero across the whole screen, its logo included. Shown with its alpha, the GUI drew the logo and the black around it as transparent - the panel's own background where the console shows a black screen and a logo.

Rejected:

• Keeping the alpha for titles that write one: no title's alpha is ever composited on the hardware, so there is no title for which it would be right.
