Value renderer twice when scrolling

Hi,

We have a grid with about 40 columns and expect to have 250-300 rows in the grid.

Noticed that when scrolling to the right, it becomes sluggish for a second or so. Then after that, the value that is rendered earlier in the scroll re-appears in the cell later in the scroll.

The feature we are using:

  • nestedHeaders
  • fixedColumnsLeft

Are there any suggestions to improve/fix this?

Thank you for your cooperation

Hi @jumpei.yamauchi
I have prepared an example with those two features here: http://jsfiddle.net/sdhnyuja/
Can you instruct me how to reproduce the bug?
