Hello,
the Topic says everything.
I tested it under 4.4.0, 4.4.1, 4.4.2 and 4.4.3 but no results.
The Vaadin Sample grids are slow aswell in Firefox with the scroll wheel. The OS dont change anything Windows, MacOS and Linux no differences.
If you use a touchpad and “swipe” it works, but not with a scroll wheel.
Any kind of answers would be awsome Thanks!
