ImageQt does not work as expected in PyQt5 #5266
Description
What did you do?
Attempted to use ImageQt to load a Pillow image in a PyQt5 application
What did you expect to happen?
I expected the image to load correctly. There are no errors, but it does not load the image in PyQt5 correctly.
What actually happened?
The image loaded as a mostly white image with kind of ghost image of the actual photo (see screenshot). I have attached the PyQt5 and PySide6 code, including screenshots from when I ran both files.
Note: The same code works in PySide6, but not in PyQt5.
What are your OS, Python and Pillow versions?
- OS: MacOS Mojave and Windows 10
- Python: Python 3.9
- Pillow: 8.0.0
