--- Comment #14 from V Stuart Foote <vstuart.foote at utsa.edu> ---
Checking with a Windows Surface Pro 4, at full 2736 x 1824px resolution ~275ppi
and 200% UI scaling the icons are corrupted--Alpha channel incorrectly treated
as a mask as Noel suggests?

But same hardware, with screen resolution reduced to 1680 x 1050px ~165ppi and
100% UI scaling--all icon themes render cleanly.

Same hardware at 1680 x 1050px ~165ppi, set UI scaling to 150%. The icon theme
corruption occurs.  At UI scaling of 125% (so the 32px PNG are used, right?),
no corruption.

So, not the absolute ppi value of the hardware, or as set from the DE. Rather,
issue here seems to be any scaling/reparsing for any icon theme cache being
pulled from SVG. Guess the Sifr icons are just not affected by an alpha channel
based mask.
