Weird artifacts in Metal Gear Solid Peace Walker

[milweekmoon]

Backend: OpenGL(This problem doesn’t seem to happen when using Vulkan)

PPSSPP: Version 1.9.3

OS: iOS 1.13.5 Jailbroken

Device: iPhone XR

This is what it supposed to look like:

This might be a stupid question but I can’t find any answers online. Will Vulkan as Backend ever come the ppsspp on iOS?

This is the frame dump of the game:

Related #12990?

Could you create a frame dump.? Doesn't matter if the frame dump is created on PC or Android.

I can answer this for now. Apple is pushing hard to use its Metal API and deprecating OpenGL. So NO Vulkan for iOS

May I ask, what phone are you using? Is it Android or iOS?

Ah, Android. This problem seems to only happen on iOS devices. Every video of msgpw on iOS seems to have this issue as well but I have never seen this problem on Android.

Has this improved in the latest git builds?

This could've been related to the IR interpreter fixes (maybe, probably not) or the flat shading driver bug.

Dude it’s been like half a year since I posted this problem but still, thanks for commenting! I have no idea if it’s been fixed since I gave up after a while but I am going to try again now.

This should be fixed now via #16396 or not?

Okay, I'm going to assume there's a good chance those changes improved this especially given #10650. Will close.

If you're still seeing exactly this bug please comment and we'll reopen. If you're seeing another bug in the same game or a similar bug even, please create a new issue.
