Our state of the art Gantt chart
I am experiencing some sluggish scrolling with the Gantt chart. I was expecting to have a smoother scrolling experience similar to that of the big data set example on the examples page. The scrolling isn't as smooth and there seems to be a delay. I also noticed that the dependency connectors seem to be redrawn or flicker whenever I scroll.
I am using the following packages.
"@bryntum/gantt": "npm:@bryntum/gantt-trial@4.1.2",
"@bryntum/gantt-react": "4.1.2",
Attached is the sample data I am using.
Videos are not permitted? Otherwise I have a video of said behavior.
Take a look at the following video. It is a sreencast with your configuration/data, production build with our latest (yet to be released) 4.1.3
version and licensed version, no trial. It seems quite snappy to me, what do you think?

Yes that looks much better than what I am experiencing. Have you tried using 4.1.2 trial version to see if it could be replicated?

Thanks very much for confirming.
Just to confirm, licensed versions 4.1.2 and above will not have the choppy scrolling and this is exclusive to trial versions only?
Yes, according to my tests, it is so.

Does it get more sluggish the more records you add to the store?
I've increased my data to 500 tasks and it became extremely slow. Its slow loading the data and scrolling vertically/horizontally.
Give us please your runnable showcase, we'll re-test on the same conditions as above (latest release, licensed version).

The versions are the same as the original post.
"@bryntum/gantt": "npm:@bryntum/gantt-trial@4.1.2",
"@bryntum/gantt-react": "4.1.2",
I attached a working sample.
Thank you for the data. We will discuss it internally and will answer early next week.
