Original GitHub issue: https://github.com/rivo/tview/issues/401

Compiling any of the demos on windows and trying to run the exe both directly and through cmd, powershell, and Windows Terminal, the UI does not refresh after resizing at all!

I have to manually press a key for the UI to refresh.

Editing application.go and adding screen.Sync() before newWidth, newHeight := screen.Size() seems to fix it?

Not sure exactly why this issue is happening?

According to the tcell docs on Screen.Size:

Size returns the screen size as width, height. This changes in response to a call to Clear or Flush.

Clear was not being called before retrieving the new screen size. I've submitted a PR to resolve this.

I made the change that @tslocum suggested. This will hopefully solve your problem. If not, please open a new issue. (I might not see it here anymore.)
