Neither of the above descriptions is familiar to me, and I have three TFT screens on 520c and 540c Macs. In my experience, the colour TFT displays of the PB 500 series, as opposed to the entirely expectable behaviour of the FSTN displays, are exemplary both for themselves and as products of their time. Even the pointer submarining of the latter is able to be ameliorated, if not overcome.

Perhaps a pic. ot two may be enlightening. (Groan.)
