Wiley Fox Swift X 2 Adreno 505. Visual and gameplay settings as default. When approaching an ocean biome performance decreases until game becomes unplayable. FPS reports as 0.0. Memory usage remains constant. It appears to be rendering distant objects. Performance gradually returns if character remains at a specific x,y,z coordinate. However any movement results in decreased performance. Moving away from ocean biome returns performance to normal. Occurs regardless of whether experimental features are enabled or not. Has been occurring since version with pretty bubbles, although still occurs with this option switched off. Restarting game does not fix issue. Is consistently reproducible.
