Green tint when using powervr filter with VGA cable mode #1168

Open BParks21 opened 2 years ago

BParks21 commented 2 years ago

When using the powervr2 post processing filter with the VGA cable mode there is a strong green tint. The tint does not appear with the filter off. The filter on does not generate a green tint with the other two cable modes. Is this normal?

Yeah, I tried to replicate the issues with real VGA output off a Dreamcast, so there's some ringing bleed, some green, but I didn't implement the annoying interference. It could be split off to an option since it's not really a PowerVR2 process but a signal defect, IMO

Now when it's enabled I just get a black screen.

This appears to be fixed

Still getting green tint on my end, in every output mode (VGA, TV RGB, TV Composite). The only way to get rid of it is to turn off the powerVR filter. BTW, what does this filter supposed to do?

Is your core up to date?

Daemit commented 4 months ago

As far as I can tell, yes. Updated it through retroarch updater. Core version: 7d64554

The green tint is most noticeable on black screens or dark scenes with lots of black.

I can't reproduce it what games are you testing?

Daemit commented 4 months ago

Alone in The Dark The New Nightmare, Resident Evil: Code Veronica X, Under Defeat. I can make screenshots, if it helps.

BParks21 commented 4 months ago

Yeah let me see some screenshots. Also list your settings for the core. I tried Alone in The Dark, don't see anything.
