When I enable the web brower plugin, the packed game with fullscreen mode seems to be weird:
The window is not fullscreen and is placed on the up-left corner of my screen. When I disable the web brower plugin, the packed game works fine with fullscreen mode.
I tired this web browser plugin in UE4.27. Everything works fine and there is no problem related with fullscreen mode.
So I guess this may be a bug of UE5.0. Can somebody fix that? Thanks!
