This seems to require:

It may also look better if you try 1x PSP render resolution.

OK I'll do that

ghost commented 5 years ago

@unknownbrackets I tried what you said but didn't help to minimize the issues :/

This issue is unfixable in my device should I closed this ?

ghost commented 5 years ago

The issue also appeared in Mali-T720 GPU so I think this is a driver bug?

closing :(

hrydgard commented 5 years ago

I'm reopening because any dual src blending issue can be worked around - with quite a bit of fiddly GPU work though.

Flickering still happen in the latest builld (1.9.3-369) using default settings

ghost commented 4 years ago

Maybe you will implement like this, like dolphin did to fixed src dual blending? https://github.com/dolphin-emu/dolphin/pull/6141

@Gamemulatorer any updates for this?

ghost commented 3 years ago

The screen still flickering on OGL but not on VK

Panderner commented 3 years ago

@Gamemulatorer can you check the OpenGL ES version?

ghost commented 3 years ago

OpenGL 3.2 Redmi 9 G80

ghost commented 3 years ago

I think this issue is kinda related to this #10726

ghost commented 3 years ago

No screen flickering using ppsspp v1.0 Screenshot_2021-05-03-19-35-21-777_org ppsspp ppssppgold Maybe the cause of this issue is same as MonHun Nikki As explained below.

If 42bcea7 is the first bad build, and a9ff7c2 is the last working one, then it must be the difference between / 65535.0f and * (1.0f / 65535.0f)? I'm guessing that means it's something that is near outside the depth range.

Vulkan probably works because of accurate depth, then.

Interesting, it's like you're getting a truncated message or something. I wonder what could be causing this...
