I am currently playing the FTB Skies modpack (Minecraft 1.19.2 with Rubidium 0.6.2a). However, I have noticed that the option to animate only visible textures of Rubidium works partially. Some textures such as the Nether portal do not get animated while others have slow animations.

UPDATE: By activating mixin.features.chunk_rendering, this issue has been resolved and there has been a noticeable increase in FPS. It’s interesting to note that this mixin is disabled despite being one of Sodium’s main optimizations. However, I understand that some visual glitches (from the block face) occur in some mods, but they don’t bother me enough to keep this mixin disabled.
