Tkinter StringVar memory leak?

[qhangfan]

Bug report

Bug description:

I wrote a stock data display board using tkinter, which refreshes the textvariable of a Label after receiving new stock data.
pyton code：

stock_price=StringVar()
'''
Sorry I can't provide an interface for stock data because it contains account information. In short, you will get a variable called last_price
'''
stock_price.set(last_price)

I tried many times, but the memory usage kept increasing due to the high frequency of changing the 'textvariable' of the Label component.
I hope this can be fixed, thank you very much.

CPython versions tested on:

3.12

Operating systems tested on:

Windows

Sorry, but I think it's can't be fixed without a good reproducer from you. BTW, 3.12 is only for security fixes.

Hi @qhangfan. We'd like to fix any memory leak that exists here, but there's nothing we can do without a way to reproduce it. If you can provide us a minimal example that shows the leak without relying on anything but the standard library, we'd be happy to reopen the issue and hopefully fix it, but until then I'm going to go ahead and close the issue.
