Outrun 2006 C2C: Glitches in BUFFERED graphics mode / latest git build

[TeamPandory]

What happens?

When selecting buffered / graphics settings, texture glitches on cars. Get pink cars instead of red, other cars also display strangely. Earlier psspp 1.9.1 worked fine

What should happen?

Textures should display red / real colours

What hardware, operating system, and PPSSPP version? On desktop, GPU matters for graphical issues.

Tried win10 both x64 and 32bit, PPSSPP v1.10.3-461-g0752e7d15 both x64 and x86 versions Geforce 750ti and 1060 - same issues.
Looks like:

Should look like (or similar to) - unbuffered mode

@emuchicken last build worked?

[TeamPandory]

Yes. I believe so

[Panderner]

@emuchicken don't close it when it's not fixed. any last build worked for previous versions of PPSSPP?

This issue was fixed in #13640 for Vulkan, D3D11, and GLES3 (and desktop OpenGL), but it is worth noting, however, that GLES2 and D3D9 still have the problem (and maybe always will?).

[Panderner]

But how about this?

Disable slower effects on:

Disable slower effects off:

Top picture looks ok-ish to me? If it looks wrong in "Disable slower effects off", that's ok, that setting will break graphics to gain speed.

Anyway, water is still not solid - sometimes it works, sometimes it doesn't, I don't understand it. Although this issue is not about that, so I'm gonna close it.

but how about the screenshot for real PSP?

[hrydgard]

Actually the top one looks like it has some of the blue tint from before my latest fix... Hm. Might be related to the error seen in #13639

[Panderner]

it seems the black tint still wrong.

[hrydgard]

Yeah that's no good, but this should help, hopefully: #13646

[Panderner]

The latest build broke again:

[hrydgard]

Alright, i've figured out what's going on there, we're using a ES 3.1 feature in ES 3.0. OpenGL standards documents are such a mess, really hard to find out which GLSL ES version something appeared in... turns out packUnorm4x8 is a 3.1 feature while packUnorm2x16 is a 3.0 feature. Go figure...

Gonna fix it soon.

[Panderner]

The color reflection is now fixed by #13669.
this can be closed now
