there is a memory leak in the 10.x releases that should be fixed in 10.2.0, which isn't out yet, but this version specifier should allow 10.2.0 to be installed when it's released python-pillow/Pillow#7540

Hi :)
I have found a memory leak when drawing text with Pillow.
How to reproduce
Docker run command (example)
docker run -it --rm --name pillow_python_test -v "$PWD":/usr/src/myapp -w /usr/src/myapp python_for_pillow python test_pillow.py
python_for_pillow is my docker python:3.8-slim image with Pillow (10.1.0) and psutils installed.
Python script to reproduce the memory leak (test_pillow.py)
This code outputs the RAM usage every 10 seconds. Example output:
The RAM usage is increasing by approximately 2 MB every 10 seconds. This does not happen when drawing rectangles. If you replace the for loop with while true, the memory leak can be observed as well.
The text was updated successfully, but these errors were encountered:
