[replay] Background is not drawn during the loading screen of some apps

[ziga-lunarg]

There are multiple android games where during the loading screen in the replay the background will just be some green color, which I assume is the clear color. Happens with trim and without it.

Could it be an uninitialized AHB buffer? AHB can be left uninitialized when at capture we fail at locking them and dumping their content, AHB is a weird format which we cannot regenerate at replay and perhaps other reasons

I have not thought about that, but good idea, I'll check it out

The games that have issues with the background rendering do not have any AHB warnings. And I wrongly assumed the green color was from a clear, it's actually a draw.

I remember seeing a green background in the NiNoKuNi game, there was supposed to be a video playing in the background in the game's main menu but when replaying there was a shade of green instead of the video. I don't remember how exactly this failed but it was because of a weird AHB format which is not in the list of supported AHB formats

I wonder if we could (1) save a checkerboard or maybe even the text "AHB Not Saved" if we can't lock the buffer to read it out and (2) checkerboard or "AHB Not Replayed" if we can't create a buffer with the saved format.

We definitely print a warning (used to be an error) when we can't lock the AHB, during both capture and replay
