Checklist
- [X] Test in the latest git build in case it's already fixed.
- [X] Search for other reports of the same issue.
- [X] Try resetting settings or older versions and include if the issue is related.
- [X] Try changing graphics settings to determine if one causes the glitch (especially speed hacks or enhancements/replacements.)
- [X] Include logs or screenshots of issue.
Looks maybe like a polygon crack between different meshes due to precision issues? have you checked that it doesn't happen on the real PSP?

IDK if this also happen on real psp because I don't have one :(.
Another glitch I found in the stars burst jelly fish but can be workaround by PixelDepthRounding

The line at least seems to appear on the PSP as well, so I think that's a game bug:
I've got something else going on with Vulkan, but the line is correct:
Direct3D 11 looks right, though:
Here's software:
Definitely something weird happening there.

There's also a shadow flickering

I notice that there's no HUD using opengl backend.
OpenGL
Vulkan
This game also sometimes freezed/hang using opengl SBSPTT.ppdmp.zip
I don't reproduce any hud problems. Can you confirm this is with vertex cache disabled?
My previous Vulkan issue is gone now, I think it was a culling bug.
Software is still broken. The problem draw is 55. If I skip that, there's still some aliasing around the main character, but the light blue splotch is gone.
The draw in question uses:
- Depth test, src >= dest
- Depth clamp OFF
- Minz 0x0010, maxz 0xfff0
- Viewport Z 32768 with scale -32752 (so 1.0 -> 0x0010)
- Full transform
The resulting draw produces Z values in the range of 0xFFEB (should've been culled due to z.) Hmm...

Still no HUD using ppsspp v1.12.3-155 OpenGL

Similar to https://github.com/hrydgard/ppsspp/issues/10387
And for sure vertex cache is disabled? That's entirely with default settings on the Mali-G52?

Hmm.. yes vertex cache is disable and not available in ppsspp v1.12.3-155 using opengl and yes I'm only using default settings.

I can still reproduce this glitch using the dump.
Device: Redmi 10c Snapdragon 680 Adreno 610
Does PixelDepthRounding still help? Now it would use a compressed range of depth rather than writing depth, so it may have changed behavior - and might not be as slow.
Has anything changed with the HUD? Is this only on Android Adreno GLES perhaps?

The invisible HUD can only reproduce in Mali GPU opengl but the star bubbles can reproduce both mali and adreno.
Does it still repro in the latest builds? Does geometry shader culling help?

Cannot test as the moment because I don't have a MALI GPU phone that supports Vulkan.
