Real-time Data Line Chart Graph UI Blinking Issues

Hi.
Bluetooth receives real-time data(100Hz) and outputs graphs through a line graph library(LineChart).
The UI will update normally for about 10 minutes, but the UI will start blinking little by little and start to deteriorate (the graph will disappear and reappear after about 3 hours).
I wonder if this problem is a memory leak or if it is improved by modifying other hyperparameters.

Reproduce the issue with Bluetooth data arriving at 100Hz and the LineChart rendering continuously. Observe the chart during a prolonged run, starting with the reported blinking after about 10 minutes and disappearance after about 3 hours; done means the cause is identified and the graph remains stable.
