Good afternoon friend
I've tried everything too but I have not been able to solve this bug that is present since several batocera versions
But I've got a solution
In the main menu of the batocera va in option of games
Then go to the
Image filter set
there are two options for you to choose
Retro
Scanlines
Choose one of them and the batocera will put the best shader configuration in all emulators automatically
for PSX games in 3D and I prefer the filter- Scanlines
Already in Megaman and Marvel Vs Capcom and other games that have 2D image I use the filter- Retro
There is also active - Decoration- Automatic
to have the overlays in the accumulators so the games have the better image.
This if you're playing on a 32 inch Led Tv up
Also disable the integer Scale (Pixel Perfect) - OFF
in the Samsung TV Mine 40 Inches got better with the Scale (Pixel Perfect) - OFF
But there are TVs that look better with Scale (Pixel Perfect) - ON
there you see on your TV which will look better if turned on
There is and the screen format of the games in the batocera I left in 4/3 or auto
you also change this in the batocera games option
At that point I am using the filter- Retro for all emulators. This suggestion is for raspberry pi3 and PC
and use on my Raspberry pi 3 B
This is all I know and I shared one more hug I hope this tip is useful for you because for me it was
