[Regression] SSX Green/Blue Smoke Graphical Bug On/After v0.0.21-13531 (#11867)

[jeremybris]

Quick summary

On/after v0.0.21-13531 (PR #11867) Smoke is green, should be white/grey, specifically, on the level "Explore" > "Alaska" > "Foraker" > "Invincible: Race it". Later, it regressed again, from green to blue smoke.

My save game, if needed to replicate:

Other details

The smoke regressed again from green to blue. I can not find the build that regressed it because SSX stopped going in-game briefly. I found it's between build 15184 - 15312, probably one of kd-11's PRs:

Before v0.0.28-15183	-------------	-------------
After v0.0.28-15312	(Maybe PR #14104 ?? Explanation below.)	Blue Smoke RSX Capture

In addition, a different smoke effect is now missing (probably related, went missing at the same time:

Edit: Tried to find the second regression. Of kd-11's ~7 PR's during this time period, only this PR changes similar files to PR #11867 (green smoke). They both have changes to "rpcs3/Emu/RSX/Program/GLSLCommon.cpp", lines 23-500.

Cannot reproduce on latest master on my savefile. The save you provided is the ghost data, not your profile, so I couldn't try that. I also don't know how you're playing a daytime stage at night 🤔

Ah, thanks for the comment. Maybe an AMD GPU bug (I have AMD 6900x). To play at night, you click on "Exploration" in the main menu. It's a level in Alaska. I re-uploaded the correct save data.

Edit: Tested on another computer (AMD 6900HS, 3060 Mobile). No problems on that computer.

Just started a new save and it's night time too, so my only guess is that maybe times changed because of the Online mode? Since my save is from back when I played in PS3 guess I'm stuck with these 😄

Also still can't reproduce even with your save, so maybe it's only on AMD GPUs like you said 😕

This appears to be fixed for me on my 6900 xt, on the latest RPCS3, so closing.
