This very simple commit has a long story. See the mailing list
subject "mobile: android splash screen (and issue 513) opacity
weirdness".
There is even more. I found the following deccription on Internet:
https://falsinsoft.blogspot.nl/2017/07/qml-show-android-native-splash-screen.html
and tried to implement this with the potentially nice Qt functionality
(since 5.8) to manually get rid of the splash screen. Unfortunately,
this does not work. Notice that there are subtile differences in
the here found internet page, and the method originally implemented
in commit 04e994b575.
This fix is as mimimalistic as it can be. Just do not set black but
white for the initial background. Unfortunately, there is still
a small position change of the icon. It is known why, but solving
is left as an exercise to the reader.
Fixes: #513

This is based on post by Ben Laud
https://medium.com/@benlaud/complete-guide-to-make-a-splash-screen-for-your-qml-android-application-567ca3bc70af
It creates a theme that uses a splash drawable that Android will show
immediately when the application is launched. And then starts the QML
application with visibility set to false adn only makes it visible (and replace
the splash screen) once initialization is finished.
We still get a little flicker with the switch from splash to start page to dive
list, but over all the experience is hugely improved. And the bug that the
splash screen stays around when starting Subsurface-mobile in landscape also
appears to be fixed.
