Graphic issue starting with v0.9.5-870-g6a8123b

[LPatamon]

Hello. I was testing v0.9.5-870-g6a8123b and there is a graphic glitch on Digimon World Re: Digitize (maybe on other games too but so far on the games I played only this one showed this error):

       
Black where floor should be and also when you move the character it kinda blinks.

Here is a screenshot of the last version that showed the game correctly:

   
Last version showing game correctly was v0.9.5-868-g50f67d6

I think the problem has to do with the "Stencil-to-alpha fragment tweak: Set alpha to 0 if we can't deduce the stencil value.This fixes the weird glowing shadows in Wipeout" that got added in v0.9.5-869-g41209eb.

The build v0.9.5-869-g41209eb only has Windows 64 download, but the next one which is v0.9.5-870-g6a8123b has all three download options available and on that one the game has the glitch shown on the screenshots as well. v0.9.5-872-gcd69624 also has the graphical glitch.

I already posted this issue on the game's thread so we can have a sort of registry for the progress about any issues that may get present on this game in the future due to the constant work on the emulator, but I thought it would be good to post this on the development forum since it is the one that is visited often to see what details have been found on each build that gets released.

I think it is a pretty easy thing to fix, but since I'm not a programmer I'm not fully sure about that n.nU
