Shift in lines when creating videos using VideoWriter

I'm using VideoReader to read a mp4 video, insert a few shapes and annotations, then use VideoWriter to write a new video file. The script was working fine with matlab 2023a on an intel macbook pro. After I switch to matlab 2023b on a macbook with m3 chip, the script stop working. The video geneerated shows weird shift in lines below:

I did notice if I change the file type for VideoWriter from 'MPEG-4' to 'Uncompressed AVI", it can work. But the file size is gigantic.

Can someone help please? Thank you so much!

This is a known problem in R2023b for the Apple Silicon

Possibly it only happens when you only write a single frame to the movie; I am not sure about that.

Thanks for the answer. Any chance you might know when this known problem will be solved?

Sorry, I have no information as to when the problem will be solved.

I was also experiencing the same problem in r2023b running on macbook pro apple silicon. I fixed it randomly by adding text to the figure, even if it is just a blank string.

text(0.99*ax.XLim(2),0.99*ax.YLim(1),'','HorizontalAlignment','right','VerticalAlignment','bottom','FontSize',40,'FontName','Arial')

I believe all the options are unnecessary but just citing exactly what I did. Maybe this will help provide a temporary solution.
