Alpha Compression Artifacts

Confirmed in Main 4.22 @ CL 4586854

in 4.21 Alpha looks to be about 1 pixel larger than other channels in certain parts of the texture

"The issue is not improved by changing compression settings, using different color depths, different file types"

1. Import texture file with alpha (2 samples included one from user and one from internet (both 512px))
2. View Texture or apply to material

Result: Alpha looks to bleed beyond opaque portions by ~1px
