MacOS 14.5 Black flashing screen when presenting

[mayurankv]

Hi, I'd like to use manim-slides for an academic presentation, but I would need to be able to reliably display the presentation from my laptop. I've seen the issues around the flashing black screen (as well as the pyqt bug report) and I saw that a few of these had people satisfied with the resolution through changing python package versions etc. However, I could not identify any clearly outlined set of versions which would mediate this issue. I was wondering whether any such set of versions exists? I have installed manim-slides in a lone virtual environment and the issue still persists so I'm a bit concerned this issue isn't addressable and I wouldn't be able to use this tool.

I'd really appreciate any direction or clarity. I know this has been addressed elsewhere so I'm sorry to waste your time, but I don't think it was made clear anywhere whether this was an unavoidable issue and whether it was platform agnostic (I seem to recall only seeing it referring to windows). Thank you!

Ah, I've reread the installation in a bit more detail and found that I have to use python3.11 instead of 3.12 to address this!

Hi @mayurankv, this is indeed a bug that is documented in both the documentation, and the issue #293. However, I recently merged a fix onto the main branch (see #465). It's not released on PyPI yet, but can you test locally that it fixes that black flashing screen on Python 3.12?

You can install the fix from the main branch with pip install git+https://github.com/jeertmans/manim-slides.git@main.

Hi! Would be happy to test this out. Have a deadline I'm trying to meet so will update you when I have a chance!

No issue, reach back to me when you had time to test :)
