Game stutters (visually) when a block is placed (or broken). Seems to be correlated to how long the world has been loaded for, as it wasn't noticeable when first starting to play in world.
Persists through exiting local world and reopening, but exiting and reloading game client appears to fix/lessen.
Environment
6 cores (AMD FX 6300) cpu, AMD Radeon R7 360 graphics, display frequency 60, windowed, little endian, ~60 fps, occurs both when vsync is true and when false.
