Shin Megami Tensei Nocturne Flickering Bug

[Nero22]

Ran into a flickering issue with the water the healing room as well as with the dark fog effect in Shibuya, it occurs even in software mode. The only way I could "fix" it is by forcing trilinear filtering and disabling mipmaps, although doing this breaks rendering in some other areas.
I'm using the latest nightly builds although it also occurs in the last stable one.
Help would be appreciated, thanks.
