Thanks, that is super useful. I can imagine, it could be something like that but what causes me most headache is that each platform also has its own quirks. The native versions for windows and linux run way more smoothly for example than the web version.
I will investigate this for sure, the tooltip and specific situation you mention are good starting points. There are already quite some optimizations in the game. UI elements are only refreshed at 10Hz for example and the star map is layered depending on how often the elements should be redrawn (hexes vs. labels vs. animations).
