I repro, but only if automatic spell checking is active. Can you confirm? Otherwise it is 65-70%.

Hmm.. the STR are not JMUX proof: CPU doesn't say anything.. So it's more about page down speed & tearing..
Most problematic with spell-check enabled, indeed. Without it's little marginal slower
Btw, did I report this before.. you did measure 'a bug doc' of mine with page down a while ago?
