In the nether the bow and other graphics stop working! Flames on the netherrack cant be seen, firecharges from ghasts cant be seen either! Really difficult to play when the main functionality of the nether does not work!

The nether is not functioning properly! 
the ghast animations do not function as intended

flames ignited on netherrack are invisible

the bow does not appear and the animation does not show when drawing, however can be seen firing an arrow!

assuming that it is for enchanted bows as a normal bow when tested showed animation

attached are images showing the visual glitches
