Package: libpng16-16 Version: 1.6.21-4 Control: affects -1 wine32 wine64 wine32 and wine64 are super noisy, even when the command they run does nothing; they complain repeatedly to stderr about a modified version of libpng. this probably affects other programs that were built against libpng12 and are now running against libpng16, too.

https://sources.debian.net/src/libpng1.6/1.6.21-4/png.c/?hl=206#L169 it sounds to me like upstream is not handling abi versioning in the standard sane way that debian expects from C libraries, which is causing a lot of (maybe spurious?) warnings for its dependencies :/ --dkg
