If using OnPrepareCanvas event, try to use Canvas properties instead of grids properties, for example changing grid's font results in new whole windows invalidates, the same for grid.color. So please try to see if using grid.canvas.font(.color, etc) and grid.canvas.brush.color makes any difference.
