ElectronNET.CLI 13.5.1
ElectronNET.API 13.5.1

NodeJs version 6.14.12 (not sure if used)

Blazor Application Using net5.0 Target Framework

When I run my Blazor app as a windows desktop application using Electron, the splash screen shows, and then a blank screen shows. If I do not interact with the screen from that point, the blank screen persists and the app hangs on the blank screen.

Clicking the screen or hovering the mouse over Electron window seems to trigger the content of the page loading. After clicking I can resume use of the app as normal.

Steps to Reproduce:

Create Blazor (may not have to be Blazor) application with electron.
Add splash screen to electron.manifest.json
Run the electron app. Do not interact with the computer (i.e. mouse, keyboard) while the app is starting.
Verify the splash screen shows.
Verify a blank screen shows after the splash screen is hidden.
Click around inside and outside of the electron window. Verify the blank screen goes away.

Note: this issue occurs sporadically, so it may take a few tries to reproduce.
