P: Color SVG fonts - unwanted outline with overlapped glyphs

Hello,
I was happy when I heard that Photoshop support Color fonts, but..
I  tested my OpenTypeSVG color fonts in Photoshop CC2017.0.1 and found a bug with overlapped glyphs:
first and second glyph are rendered correctly, but third and all next glyphs are rendered with "small outline". As example:



I think, it 's problem with incorrect background color for transparent pixels on edges of glyphs.

Font used: DigitaltS-fruits: http://www.glukfonts.pl/font.php?font=DigitaltS-fruits
