When having quartz, or slime, or snow backpack in the inventory, slots behind these items with cursor above it becomes white

forge 1.12.2 2838
traveller's backpack 1.0.19.19 only
no optifine
no other resourcepacks
notebook with nvidia graphic card

p.s. ( Just minutes ago, I found that my minecraft screen becomes black except better hud's a few texts and xaero's minimap, when wearing a quartz backpack, but it didn't crash, or losing fps. It might be a mod conflict, but traveller's backpack works with foamfix, vanillafix, phosopher, and Immersive engineering. ← ( Found, it is a issue with better hud.) ( together with drinking 1000mb potion using the hose rather than 250mb, this must be a mod conflict too. ) )

fixed. thanks for your hardworking. 比心
