Merry Christmas to you as well, sir!

This note in the documentation might explain what's going on with version 3.7:

/*
New as of version 3.8, using filter all and transmit all on an image file with
an alpha channel is now supported properly (requires #version 3.8 or higher).
*/

Maybe it's time to upgrade to version 3.8...
