  • Fixed font atlas resizing state inconsistency (Fixes rare JVM crash when using certain resource packs)
  • Improved compatibility with mods which don't render into the batching buffer while batching

v1.9.3

  • Fixed linux AMD GPU flashing window issue caused by the framebuffer optimization
  • Fixed Intel GPU graphical issue caused by the framebuffer optimization

v1.9.2

  • Added new optimization: Avoid redundant framebuffer switching
    • This optimization reduces the number of framebuffer switches when rendering many different things in the world (entities, particles, block entities, ...) or the HUD to increase FPS.
  • Fixed force draw handling (Fixes compatibility with Tweakermore and MiniHUD)
  • Removed experimental universal HUD batching optimization
    • This optimization was disabled by default, but caused too many graphical issues when enabled, which are difficult to fix for a relatively small performance increase
