I have a similar problem, but with Vanilla Tweaks resource pack (https://vanillatweaks.net/picker/resource-packs/).

Vanilla Tweaks config: VanillaTweaks_r979419.zip
Sodium: 1.19, 0.4.2 build 16

Occurs in both singleplayer and on servers.

Same problem here, but i am only using the StayTrue resource pack.

Looks like it happens when mushrooms have multiple blockstates in your resource pack.
If you remove assets/minecraft/blockstates/brown_mushroom.json and assets/minecraft/blockstates/red_mushroom.json, it is fixed.

But then you don't get those nice random mushrooms, so a proper fix in Sodium would be nice :)
It does not happen in vanilla afterall.

Something else of note - this issue also occurs with Endermen.
Same effect as with mooshrooms, just with whatever block is being held.
I also tested with falling blocks, and found that there is neither flicker nor multiple blockstates.

Bug with Sodium 0.4.2, will be fixed in 0.4.3. 6b641f9
