[New-bugs-announce] [issue43347] IDLE crashes in

[Raymond Hettinger]

New submission from Raymond Hettinger <raymond.hettinger at gmail.com>:

I'm running a python.org Mac build on Apple silicon.

Python 3.10.0a5 (v3.10.0a5:b0478d738a, Feb  2 2021, 16:30:44) 
[Clang 12.0.0 (clang-1200.0.32.29)] on darwin

Periodically, Python freezes and requires a force quit.  I'm not certain but think the trigger event is the display of a pop-up box showing attribute completions.  The box is correctly shaped but filled with a solid light gray.

I suspect the problem is partly in the O/S because after the freeze, I see something similar when clicking the system  icon, so the effect extends beyond Python.  However, the problem does not occur on my Mac with Intel silicon and it does not happen with Python 3.9 running on Apple silicon.  

This has been occurring for a while and has persisted through O/S updates.  Today, it happened on Big Sur 11.2.2.   

Will try to get a screen shot and more details when this happens again.

The event occurs often enough to make IDLE unusable for classroom demonstrations or for development.
