[GLideN64 RDP] Incorrect bubble effect in Majora's Mask

[Qlonever]

In Majora's Mask, the deku bubble attack uses a frame buffer effect to simulate refraction. The lower right quarter of the bubble samples a section near the center of the screen; the other quarters mirror that sample.

It looks like either the effect isn't being created correctly in the first place, or the bubble is fetching from out of texture bounds for some reason. This problem happens with default GLideN64 settings, and I haven't been able to correct it by changing anything.
