Please provide minimal, but complete examples when possible. This works fine:
proc processRow(r: openarray[int]) =
for i in r: echo i
proc xxx(r: openarray[int]) =
processRow(r[0..9])
xxx([0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12])
Well, works fine with recent nim compiler:
nim -v

Pressing the run button in forum gives:

in.nim(5, 15) Error: type mismatch: got (openarray[int], Slice[system.int])
but expected one of:
proc `[]`(s: string; x: Slice[int]): string
proc `[]`[T](s: seq[T]; x: Slice[int]): seq[T]
proc `[]`[I: Ordinal; T](a: T; i: I): T

proc `[]`[Idx, T](a: array[Idx, T]; x: Slice[int]): seq[T]
