(Compute Shader) Garbled mess of pixels

[user18081972]

I can't find an issue for this problem specifically. So I am making this.
i'm not sure what to call it either. it happens in all games with enough 3D stuff going on and the rendering high enough, sometimes as low a 3x (Phantasy Star 0).

Is this a driver issue? Am i doing something wrong? Is my build broken?

[RSDuck]

It's probably a tile buffer overflow

[user18081972]

Sorry i'm still not sure, Did I do something wrong while building the branch? or is this a driver issue? Or is this known behavior that happens for everyone?

[RSDuck]

no it is a bug

you should make sure melonDS is running on your dedicated gpu if applicable, this happened to me when i built the compute shader branch and that fixed it (to a point, like dont try to render something at like 10x if you have no VRAM)

[user18081972]

My CPU is a KF model, so there is no iGPU, its running on a rtx3080 and it happened at 3x in Phantasy Star 0.

like dont try to render something at like 10x if you have no VRAM)

I got 10GB of VRAM

Avalon.Code.mp4

It also happens in Avalon Code at 1x compute shader resolution.
Or at any resolution really, also 2x and 3x. etc

1xChibiRoboParkPatrol.mp4

It's also broken at 1x and 2x on Chibi Robo Park Patrol.
Curiously enough, it fixes itself at 3x and 4x. then broken again at 5x+

Not sure which built of the compute shader renderer im using, i cant compile it on my PC. I am using the one that was uploaded to the discord a while ago.

[user18081972]

Anyone know if this is fixed on a more recent build?

[sandwichwater]

nop , probably will be fixed on the full release seeing as how there hasnt been a public update to the branch in half a year

[RSDuck]

I doubled the tile cache size in 5df83c9 that seems to fix Chibi Robo which has a stupid amount of overdraw on the TV effect.

[user18081972]

I just git cloned the compute-shader-renderer branch, build it (so that should be d366c40 ?)
Am still seeing the same problem at 1x and 2x. And then its fixed at 3x and 4x and 5x its fixed. and then broken again at 6x through 16x
Same for Avalon Code, still broken at 1x.

[user18081972]

Sorry i build an old branch. it is indeed fixed at 1x and 2x in chibi robo. but still broken at 6x+
