With Wine 1.9.12 on starting Guild Wars 2 I'm noticing that the launcher is in its first state black and showing only the initialization/downloading text and if I'm looking into the console I'm getting spammed with the line "err:wincodecs:PngDecoder_CreateInstance Failed reading PNG because unable to find libpng12.so.0". Installing libpng12-0 solves the issue so maybe it should be a dependency.
Most distros have that exact dependency as an optional dependency for Wine.
Case in point, Arch lists libpng as an optional dependency for Wine: https://www.archlinux.org/packages/multilib/x86_64/lib32-libpng/
So it's mostly dependent on what distro you use :)
