Ahaaaa!
Yes, I have non-ASCII characters! The characters that are causing this
are:

             position: 2465 of 4273 (58%), column: 30
            character: ⓐ (displayed as ⓐ) (codepoint 9424, #o22320, #x24d0)
    preferred charset: unicode (Unicode (ISO10646))
code point in charset: 0x24D0
               script: symbol
               syntax: w 	which means: word
             category: .:Base, L:Left-to-right (strong), h:Korean, j:Japanese, l:Latin
             to input: type "C-x 8 RET 24d0" or "C-x 8 RET CIRCLED LATIN SMALL LETTER A"
          buffer code: #xE2 #x93 #x90
            file code: #xE2 #x93 #x90 (encoded by coding system utf-8-unix)
              display: by this font (glyph code)
    uniscribe:-outline-Malgun Gothic-normal-normal-normal-sans-13-*-*-*-p-*-ksc5601.1987-0 (#xDB)

Character code properties: customize what to show
  name: CIRCLED LATIN SMALL LETTER A
  general-category: So (Symbol, Other)
  decomposition: (circle 97) (circle 'a')

There are text properties here:
  face                 font-lock-string-face
  fontified            t

and:

             position: 2832 of 4394 (64%), column: 30
            character: ⓒ (displayed as ⓒ) (codepoint 9426, #o22322, #x24d2)
    preferred charset: unicode (Unicode (ISO10646))
code point in charset: 0x24D2
               script: symbol
               syntax: w 	which means: word
             category: .:Base, L:Left-to-right (strong), h:Korean, j:Japanese, l:Latin
             to input: type "C-x 8 RET 24d2" or "C-x 8 RET CIRCLED LATIN SMALL LETTER C"
          buffer code: #xE2 #x93 #x92
            file code: #xE2 #x93 #x92 (encoded by coding system utf-8-unix)
              display: by this font (glyph code)
    uniscribe:-outline-Malgun Gothic-normal-normal-normal-sans-13-*-*-*-p-*-ksc5601.1987-0 (#xDD)

Character code properties: customize what to show
  name: CIRCLED LATIN SMALL LETTER C
  general-category: So (Symbol, Other)
  decomposition: (circle 99) (circle 'c')

There are text properties here:
  face                 font-lock-string-face
  fontified            t


If I remove these symbols from the init file scrolling gets very
smooth. So I guess the Malgun Gothic is the culprit!
