Problem with IWDBGrid Async refresh

[Comograma]

For even best results, please update to 15.2.8.

It generates a slightly better response when rendering in async

In the first place, thanks a lot Alexandre.
The IWDBGrid1.StyleRenderOptions.RenderSize := False;, like you said, work like expected and like before. Far from discover myself that it was so simple.
But now, with v15.2.8, I get an AV when the browser, any browser, loads the main page.
This is bad.
I atached a pdf with that error. Maybe you can help me. With v15.2.7 works ok.
