Hi, is it a known issue that the GUI is much slower than in e.g. 2024b? Will Mathworks work on this? Do I need to supply a screen capture with a comparison to show the difference?

- your MATLAB prerelease version (ver command would be good for this)
- a screenshot or short video of the issue if possible.
- your system information, OS, memory etc..
- does it happen overtime and its gradual or is it slow from the beginning?
- is it slow only in certain configurations? (ex: docked vs undocked)

Yes, this is what I meant!





The issue is that you need to use code section then a text gap and then a code section. You cannot use code section and then immediately a different code section: the two code sections will automatically get merged together.
I am not sure why exactly you would want two adjacent code sections, but I acknowledge that they cannot currently be created.

I made it clear a few weeks ago that there would not be any copilot in r2025a.
(I do not know if or when such a feature will be introduced.)

I was around for design discussions about this and advocated for it. I’m excited to see that it has shipped.
In the past, I have found that editing light text on a dark background was hard on my eyes, but I might try this again.
