Does Google use Filament [1] for this AR stuff or do they have something completely different? I mean using something else would be a huge waste from my little point of view ¯\_(ツ)_/¯

Yes it is using it wrong, because while some issues are indeed Swing interop bugs with the host GUI, others are lack of skills by not reading canonical books like "Filthy Rich Clients", written by Chet Haase and Romain Guy, the guys that drove most of Android rendering stack.

Romain Guy's team recently released Filament, https://github.com/google/filament

Back in the Sun days, Romain had a blog about writing nice looking Java UIs, which eventually lead to the "Filthy Rich Clients" book publication.
