I found that usually walking across the ice without frost Walker updates the block and it begins to melt quite fast

 In creative mode after loading so many chucks so fast a computer will have trouble keeping up and staying an track it will load what it can but if you just live it some time to catch up with you it will normally go back to normal functions of the loading process. Always just keep it in mind what you're computer is capable of doing and what is too much for it. [When it slows down just give it a little time to finish the loading process and continue. More that this has been an ongoing issue for long periods of eltra flight for some time now unsure if it will be resolved due to the fact if they update the game too much in this area it will lag badly on lower end computers
