After some attempts i need to summarize that rendering asynchronously on canvas is not a good idea. The canvas state can change many times until the asynch code is evaluated. The main problem is with resizing and scrolling DataGrid when the cell's coords are changing.
The better approach is to request repainting the give cell when the asynch fn is resolved.
