I’ve been dealing with this for a couple of years, and still I haven’t found a solution.
When app is initializing, after loading dialog, a blank page is shown a few seconds. This looks unprofessional for me.
I need to avoid this blank page or at least set color to match my app color.
I’ve been looking in rendering engine backgroundcolor (I still don’t know what is this for);
I tried to edit theme in ui editor (backgrounds) with no luck.
Anyone has a solution for this?
