    • Hello,

      Thank you for providing this information. This issue appears to arise due to keyboard messages causing less coalescing of mouse move messages (namely when you have a key pressed down, we get a lot more messages). The general performance of jquery $.html is being investigated, so we expect this performance will be improved in our next release.

      Best Wishes,
