Lag in keeping scrollable table viewport in sync with frozen viewport

[evansjohnson]

Steps to reproduce

This is noticeable at the table docs: https://blueprintjs.com/docs/#table/features.freezing particularly testing with a trackpad and on horizontal scrolling

Actual behavior

The frozen viewport (slightly) lags behind the scroll of the scrollable main viewport. I expect in some cases (ex many more rows/columns, or much more complex cell rendering) the lag may be much more noticeable.

Expected behavior

Scroll should be kept in sync without noticeable lag

Possible solution

Unknown

I'm not sure if it's reasonable to expect this behavior to be any better than it currently is, but opening this issue to have something to point to and track possible signal.
