Hi, I took a look at this, since this started happening after I updated wand [1] to it's latest upstream release, 0.7.0. While debugging, I found out that the test only fails with Python 3.14, running it with Python 3.13 is successful, output is attached. This same test also failed at upstream CI pipeline [2]. The willow package also has other tests related to wand in tests/test_wand.py. The test which is similar and succeeds on both Python 3.13 and 3.14 is: - test_animated_gif() - test_resize_animated_gif() For now I'm holding off on any more debugging.
