The problem is lack of an alpha channel. It's skewed in that way as it's
expecting 4 bytes per pixel but it's getting 3. You can use imagemagick
to check this:
identify -verbose terras1.png
(lots of stuff...)
Channel depth:
red: 8-bit
green: 8-bit
blue: 8-bit
alpha: 1-bit
(lots of stuff...)
identify -verbose terras2.png
(lots of stuff...)
Channel depth:
red: 8-bit
green: 8-bit
blue: 8-bit
(lots of stuff...)
In gimp the existance of "add transparency" means it's RGB, you just
need to click that and save it and it will work.
