[BUG] python -m rich.spinner "moves" down the screen on Windows #1320

[skytwosea]

This report references #1320 which is marked closed, but I am submitting a new one because the problem persists, and it is observed on a Linux platform, which is a different platform than what was reported in #1320.

When invoking python -m rich.spinner the output grows and shifts up-screen, segmenting and repeating itself in a mess of overlapping and overwritten symbols. Please see the original bug report here for more description and images.

Screenshot:

To reproduce: call python -m rich.spinner in your terminal.

Platform: Linux kernel 6.8.0 Ubuntu 24.04.1 LTS plasmashell 5.27.11 Konsole 23.08.5 Python 3.12.6 Rich 13.7.1

Diagnostics:

It's the issue described above. Updating Rich may or may not help.

It's the issue described above. Updating Rich may or may not help.

Copy that. Upgrading to rich 13.9.4 did not fix the issue, as noted.
