Monster Hunter Portable 3rd android graphic issue

[erzajumeidi]

Hi, I'm testing this game on my phone, Redmi 4a. The game is running really well, with auto frameskip enabled but then i encounter this weird glitch on the ground and plains when doing quest. I realize it happen with buffered rendering enabled. Settings are on default with Opengl backend. I test it from version 1.1 to the latest version both MHP3rd HD and non HD version and it still there, also test it on pc and only happen on phone.
I kinda unsure there is problem with my phone cause other games seems to run surprisingly well, so far. Or, something with my adreno gpu cause my other phone Redmi 2 (almost same specifications, older) encounter the same problem, or just android common issue that still unsolved. I hope there is some fix for this issue. Thanks

Is there any way to render your game in triangles? I wonder if the geometry is malformed or if it is just the shading. This looks like a common bug where two triangles are on top of each other: the two mix in a sort of scanline-like fashion.

I feel like we've seen this issue before, I recognize it. Seems to be the same:
#7218

Looks like a depth precision/Z-fighting issue. Quite odd...

When i use non buffer it looks pretty normal, but still kinda curious why in buffered rendering this thing happen...

Oh just for information, both adreno is using open gl es 3.0.., maybe there somewhat something about this cause my pc is using open gl 3.1 and it doesn't have this issue. Hope that helps, and i hope this fixed in the future

FWIW this visually looks similar to the lighting issue in Blade Dancer (see #4140 (comment)), the screenshot is clean, but depending on how you rotate, you get that banding. It does look like z-fighting, but I wonder if it's the same issue.

How did you boot up the game

I wonder if this is because floating point cancerism.

Could you try exporting a GE debugger dump on PC?

To do this, open the game and select Debug -> GE debugger..., then when it's displaying the scene, press Record in the top right. After a second or so, it'll finish and save a trace of the drawing activity.

After that, check the memstick/PSP/SYSTEM/DUMP folder and it'll have created a file named something like "ULES12345_0000.ppdmp". You can zip that and then drag and drop it into a reply here.

I think this issue already fixed in the latest build 🤔

Okay, let's hope it got fixed by the same changes that fixed Blade Dancer. They looked similar.
