[Regression] Virtua Fighter 5 FS rays of light rendered as big red boxes
Quick summary
Visual bug that produces big red transparent boxes in some stages.
Details
Since version 0.0.33-17011-48322673 these big red boxes appear in some stages. They seem to happen on daytime stages so they might be incorrectly rendered beams of lights or something. The brighter the stage, more opaque they seem to be.
Between versions 16999 and 17011 exists also 17006 and 17010, but builds for those were not available, so I couldn't test them.
Build with regression
v0.0.33-17011-48322673

How does it look with OpenGL?
on steam deck i'm on rpcs3 latest current version and setting the gpu to openGL won't even run the fight. it runs the game but when i select chars/stage it will stuck on loading screen
How does it look with OpenGL?
Imanaged to load to the training mode on OpenGL, but the stage is darker than it should be and most grabs crash the game.
AMD follows OpenGL swizzle convention when sampling borders. NVIDIA just ignores swizzles for border sampling. I don't think either one is right, but I'll just add a workaround to normalize based on real-world testing. Does anyone have an arc card we can use to test this? I'll assume it behaves like NVIDIA in this one and move on if not.
Looks like we can define the rules using an extension: https://registry.khronos.org/vulkan/specs/latest/man/html/VK_EXT_border_color_swizzle.html
