UI seems to be broken and not rendering on macOS desktop using latest master (Channel master, 3.1.0-0.0.pre.799, at the time of writing this).

Steps to replicate:

  1. Create a new Flutter app (flutter create macos_issue)
  2. cd macos_issue
  3. flutter run -d macos and observe that UI is not rendered and shows a blank screen. If we try to resize the app window, then it shows flashes of the UI as we move the window size:
macos_desktop_broken.mov

The same works properly on latest stable (3.0) and beta (2.13.0-0.4.pre) as shown below:

macos_stable_rendering.mov

Moreover, this seems to be only happening on macOS desktop, whereas, macOS + web, macOS + android and Linux desktop seems to be working as expected.

master flutter doctor -v
