What happens?

The walls & objects became visible in front of the camera perspective

What should happen?

Should hide the wall or object

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

Version: Any 1.10.3 build (including the latest from Buildbot)
GPU Backend: Vulkan & OpenGL
Hardware: Intel HD 4000 & 620, Qualcomm Snapdragon 636
Platform: Visible on both Android, Windows & MacOS as well

Additional note: I am using the HUD HD texture pack. That is not relatable to this issue

@jcchikikomori have you turned off texture replacement in development tools?

@jcchikikomori have you turned off texture replacement in development tools?

Yep. Still exists. Again, that was not the one affecting this issue

[jcchikikomori]

I just found out that Maximilian Dood has also experienced this kind of glitch. That was his re-play of Crisis Core this year

@jcchikikomori investigate that when the last build works.

Probably related to #12060

Could you try exporting a GE frame dump? These help a lot. Just make sure to export it when you see the issue - it's almost like a screenshot. If you make it while the issue isn't happening, it won't help.

See here for instructions - it's not hard and works on Android too:
https://github.com/hrydgard/ppsspp/wiki/How-to-create-a-frame-dump

You can zip that and then drag and drop it into a reply here.

I suspect this is related to #12058 and would be fixed by the same fix, but a frame dump - or a save and specific instructions on exactly where to encounter the bug - would help to verify that.

The depth clamping changes of v1.13 should have fixed this (apart from Direct3D 9).

Well, I think this is probably negative Z clip but would need a frame dump showing it to be completely sure. I don't think Crisis Core uses a narrow depth range so it wouldn't be clamping.

If it is negative Z clip, it is only solved for devices with user clip spaces or geometry shaders, which is a lot of devices but not all.
