As you can see in the first and second screenshot, the pie chart has gotten so big that takes up half the screen and sometimes you can't even see the pie chart as shown in the second screenshot. The third and fourth screenshot are showing what the pie chart looked like in previous versions

To recreate this bug all you have to do is open the pie chart in the latest version with f3 + 1

Once you open the pie chart you can press the number by "tick", then press the number by "level", and then press the number by "entities" to recreate the bug shown in the second screenshot
