Description

When Blazor Hybrid app is launched on Windows, MAUI displays two additional screens before showing Blazor content:

  1. White blank screen
  2. Gray blank screen
  3. Only now Blazor content is displayed

All happens in a fraction of a second causing effect of flickering.
Is there any way to eliminate this effect, or at least set some fixed background color to first two screens?
