Fix Missing Colored Backgrounds in Your Hotbar
Identify the Conflict
If you're using the ImmediatelyFast mod alongside RarityCore, you may notice that colored backgrounds disappear from your hotbar or appear with missing textures. This is a known compatibility issue between the two mods.
Disable HUD Batching
Open your ImmediatelyFast configuration settings. Locate the HUD batching option and turn it off. This setting controls how the mod renders heads-up display elements, and disabling it resolves the texture rendering conflict with RarityCore's background system.
Verify the Fix
After disabling HUD batching, return to your game and check your hotbar. The colored rarity backgrounds should now display correctly on all items, matching the colors shown in your main inventory.
Alternative Compatibility
If you use EMI (a recipe viewer), you may also need to disable batch processing in its settings to ensure backgrounds appear properly in recipe tabs. Check both mods' configuration menus if you continue experiencing display issues.
