Transparent Graphics not Displaying Properly
As of the the 1 - 26 - 24 update it seems there's an issue with alpha channels for match graphics.
Running on Win 10, playing through Steam.
The Cave Raptor pet's feathers have a black box around them.
The Lantern Giest pet has a white pixelated outline.
The NEO full art lands are missing the characters for each land type.
Attacks show a partially opaque box around the attacker's arrows.
All the card outlines have severe Aliasing.
Not shown, in the pre-match mulligan screen is a grey opaque box around the whole match screen, just below the cards in hand.
Nothing effecting play, but figured I'd ought to document these issues since they are on paid cosmetics.

I second that, for a while now.
