How can i fall back to pyqt6.9.1 version when installed by pypi?

Anki Help
1

Hi, i’m the maintainer of snap anki package.

I’ve noticed a blank main window issue with the latest version 25.09, while the previous build, the version 25.07.5 doesn’t have this issue.

After comparing, I’ve discovered that this might be due to the PyQt6 being updated to 6.9.2. I’d like to know how to revert to PyQt6 6.9.1.

Any help will be appreciated, thank you.

And this issue can be resolved by switching the driver to vulkan or software.

Since OpenGL is the default option and most users should be using the default option, so still need fix out.

I am not familiar with how snap packages are built. But, the following might be relevant.

Tried revert to 6.9.1 but the problem persists.

Keep getting these error messages.

Starting main loop...

Have you tried downgrading pyqt6-webengine?

Yes, did.

But unfortunately it didn’t work.
