Hi.

Thank you for great lib.
Can someone help me, maybe, please. When I try to recreate table in my grid, I have some artifacts. How I can fix it?

The gist is not a complete runnable. It is difficult to test.

Wrap any screen changes/updates in the app.QueueUpdateDraw(func(){}) handler so that the screen updates happen on the main UI thread and the re-draw is called.

Thank you for help and sorry for my bad example. I will try to create runnable example some later.
I was try to execute QueueUpdateDraw, but my app just frozen, when I try it like this:

t.App.QueueUpdateDraw(func() {
grid.AddItem(secretsTable, 1, 1, 1, 1, 0, 100, true)
})
