I am using Calculator version 10.1812.10048.0, the latest version at the time of this writing.

Describe the bug
When I click on the negate button (on the bottom left hand corner) more than 10 times, the UI of the calculator becomes slower and slower to use. The more I click on it, the slower and slower the Calculator gets, until it gets so slow it is unusable.

Steps To Reproduce

1. Open Calculator
2. Switch to Standard mode
3. Click the negate icon (the +-) thirty or more times
4. Hover over another digit on the calculator and click it. The digit will not appear in the calculator window until a few seconds later

Expected behavior
Clicking another digit should be almost instantaneous after clicking negate thirty or more times.
