New submission from Jonathan Lahav <j.la...@gmail.com>:
Observation:
After creating around 10000 widgets (verified with ttk.Label), no more widgets
get created, and sometimes graphical artifacts appear outside the application
window.
No error message or exception is raised.
Expected:
Either the limit can be removed (having dynamically created 10000 widgets in
data heavy applications is sometimes desired), or at least document and return
runtime errors to prevent the weird behavior.
Reproduction:
This is the problematic part:
for _ in range(10000):
ttk.Label(root, text='problematic')
A full minimal example code is attached, though a better effect can be seen
when running the above two lines in the context of a more advanced Tkinter
application.
