im seeing a white line border around blocks it just sundenly happend, have no idea how to fix it, iv googled it also, but nothitng any help?

Can you be a tad more specific? Maybe a screenshot?

Not really sure what your problem is, but it could be you've activated a debug option accidentally. One of them puts little white boxes around dropped items and other entities, not sure if there is one for blocks. Anyway, some buttons to try pressing. Could be fun.

f3 + B toggles entity hitboxes (white boxes around entities)
f3 + T reloads all textures (could be worth a go)
f3 + C makes a debug crash (because... why not?)

Not sure if that works for you but if you are using a geforce or other nvidia cards this might help

Seems like you have pressed something to get Hitboxes on.

i have no idea what i have pressed :/ just happend XD but thanks for the the suggestion guys
