From my understanding of the bug, this is correct and the workaround is
to adjust the xoffset as you have done. (And since the chunk is limited
to less than 32k pixels wide, adjusting the chunk width is not going to
cause an overflow.)

The code was correct and the new assertion was a little overzealous,

The 64B alignment for pitch is only applicable to linear scanout, iirc.
