PlayStation Home - MLAA issue, flickering flat color and black screen.

PSHFigment commented 2 years ago

Quick summary

PlayStation Home MLAA rendering isn't functioning as intended (NPIA00010 & NPIA00005 1.86, retail and developer.)

Details

PlayStation Home MLAA colorful screen issues when using PlayStation Home, things to note.

PlayStation Home developer version NPIA00010 (1.86) has command MlaaEnable '0'/'1' allowing you to enable and disable MLAA, this fixes the issue but completely disables MLAA, you can press select, open the debug console and input command.
If you enable 'Write Color Buffers' and 'Read Color Buffers' it isolates the issue to the left side of the screen completely and appears primarily when a user interface element is present, a comparison will be attached showing the difference between the RPCS3, Write Color Buffers on and off, as well as the PS3 version.

this seems to be triggered by text or overlays showing on screen NPIA00010_screenshot_2022_04_09_13_37_48

It isn't always the case unfortunately, with Read & Write Color Buffers disabled, it happens everywhere and is directly correlated with MLAA and using the MLAAEnable '0' command gets rid of it, when you have them both enabled, it happens when messing with ui elements and it's occurring only on the left in a similar manner.

(MLAAEnable '0', no ui elements present. Read and Write color buffers disabled.)

(Read and Write colorbuffers disabled, no ui elements present with MLAA enabled in-game.)

@Whatcookie A patch would be a good temporary workaround. None of the existing MLAA patches work on Home.

Seems like the SPU hash is different:

Just a note, but having all 4 color and depth buffers enabled is how a PS3 operates. Issues such as your black screen are not considered valid if they get fixed by enabling buffer settings. So the remaining issue here is the normal buffer being shown on left side and the flickering black square.

I presume you've already tested strict rendering mode?

Still displays with strict rendering enabled, yes.

Worked beautifully, we appreciate it.

Workaround with a patch != fixed. Keep it open until it actually gets fixed.
