Also #5664 (comment):

---

MINGW32 CI failures could be related to msys2/MINGW-packages#9771 or msys2/MINGW-packages#9736?

And at least the Tests/test_qt_image_qapplication.py::test_sanity one is intermittent (or fixed).

Here was a failing build:

https://github.com/python-pillow/Pillow/runs/3913969875?check_suite_focus=true

It passed when restarted:

Fix for the second part, failures on PyQt6 which we weren't testing on CI: #5775

[nulano]

I already noticed the first part failing intermittently in the past few days even before the release, but didn't look into / open an issue as I feel like it might be an issue with the MSYS2/MinGW build of Qt.

[hugovk]

If so, then upgrading to PyQt6 in #5775 will fix it. 🤞

I'll mark that PR as fix then and we can reopen if necessarily later!
