Maybe you are seeing palpable lags? I=E2=80=99m using macOS with the builtin trackpad, and = scrolling is pretty snappy. Maybe this only happens on Linux? I=E2=80=99m also = seeing random error faces (albeit not on brackets), could this relate to some particular way pixel-scrolling works? Does pixel-scrolling do anything special comparing to normal scrolling when fontifying text? Thanks, Yuan
