Hmm, for me, within seconds, two characters at 0F1B and 0B1B change to 'O' and then usually stay that way. Pre-47pF, they would have kept on changing every now and again between 'O', '/', '_' and occasionally '?', all characters whose codes end in 'F'.

As mentioned I will try raising to 100pF tomorrow.

(Note offset is 0x1B, not 0x27 as stated earlier - I keep forgetting that the offset is defined in decimal in the source)
