Summary0000682: Dropping large batch of ice into the stone layer (embarked on a glacier) didn't melt all the water at once.
DescriptionThere were large square chunks of ice sitting in the water while the melted water flowed around in the pit I created to catch it. I didn't match the exact size either so in the beginning the water rushed to fill those spots. Afterward, my FPS plummeted to 1-3 fps when not paused.

This continued for quite awhile until I got a message saying there was a snowstorm at which time the remaining ice melted instantly. The pool was mostly 7/7 with some 6/7. Also the FPS returned to normal.
Steps To Reproduce1. Embark on glacier
- Tough to survive sometimes. I had 6 picks, a speardwarf and some war dogs assigned to survive the undead polar bear attack.

2. 33x33 room with 31x31 channeled out in the middle
3. Drop a 29x29 block of ice in the middle.
Additional InformationAlso I noticed that there were ice "stones" floating in mid-air after the collapse.

More to it:

I dropped a 8x8 block of ice into a 8x8 stone pit and it stayed ice. Once a snowstorm hit, it instantly turned into water. In fact, there was excess water that went over the sides of the pit for some reason (ice melting takes less volume not more).

Ice dug out on top of the 8x8 block of ice was still floating in air too.

and you're saying it's a huge hit on the frame rate until it melts ?

It did in the first case because only some of the ice melted and the water was for some reason very turbulent. The 8x8 didn't have the frame hit from what I remember.
