It looks like this might be an issue with caching. I suspect because the splash screen loads as one of the first things the engine does, it tries to render the first splash screen before the images for it have been cached.
A plugin that pre-caches specific images might resolve this, but otherwise the fix would be to apply a brief wait period on the splash scene before any splash screens are supposed to show. It might only take a few frames, so it could be nearly unnoticeable.
I'd try a precache plugin first and see if that helps at all. Patching the plugin is also an option, but I haven't had a lot of time for updates lately, so you might be stuck waiting a long time for something that could be a real simple fix.
