Video artifact - Digging (Snow)

[mvgulik]

Different graphs card, different issues. (lol)

Occasional short black-ground artifact after finishing digging for snow. (direct Dig action)

(Time: left to right, fps ~30)

(Ender client. Not checked against default client. (maybe later))
(Dig: only checked against snow digging.)

+ Also seen on Default client.
+ Also seen with:
++ Area-digging (snow).
++ Soil being absorbed by snow covered ground.
+ Game Video settings: None seem to make a difference in this case.
+ Feels a bit it might be related to some cache-map-file action. (only reproducible a few times (1..3) per given area ... so far)
++ The black area is actually 25x25 in size (ground visibility block).

[algorithm]

it's because server sends signal to client to rerequest this area again + network lag, so you see that.
