I just tested in mupen64plus with FBInfo:

It's broken without FBInfo, and it still flickers between images, but I think angrylion might do that too.

The interesting thing is not even synchronous buffer copies fixes the issue, only FBInfo. I just tested angrylion and it works the same, so basically with FBInfo it works the same as angrylion. I'm not sure about 1964 or mupen64, only tested mupen64plus (with fixed FBInfo, still a PR over there)

[gonetz]

Cool!

As I remember, the game does not copy background image at one step. Half is copied in one frame another half in another frame. Thus, even sync copy does not help.

An interesting example of how FBInfo can improve accuracy.

[weinerschnitzel]

Interesting indeed. However, Wouldn't this mean that while in sync copy, the buffer is getting cleared too early before the rest of the contents are copied in?

What does the copy look like when you step through frame by frame with FBInfo?

Maybe, I think sync copies should work in theory. Even if it's not copied in one step. The whole image should still be in a buffer on the gpu at some point

[olivieryuyu]

it is not linked to interleaving somehow?

looks similar to https://github.com/gonetz/GLideN64/issues/617#issuecomment-549803363
