Typing in the live editor is slow on Linux
31 vues (au cours des 30 derniers jours)
I just installed MATLAB R2018b on Linux Mint 19. I am used to using it on Windows, where the Live Editor works great.
On Linux however, there is a very annoying latency when typing. Whether it's in a text area or code block, there is maybe ~0.25s between the time I type and when something happens on screen. I tried disabling the Datatips, which didn't help.
What's going on, and is there any way to fix this? I am running on a fast computer, so performance should not be an issue.

MATLAB R2021b now uses the same technology for regular scripts and files, not just Live Scripts. Now all editing/scrolling is painfully slow, not just in Live Editor.

MathWorks have fixed this in R2019a Update 2.
Not only Live Editor now works fine, but also Help Browser runs very smooth.

Well, I just installed Update 2 and the problem seems still present on my Ubuntu 19.04 machine. Are you, Mikhail, on Linux?

I also confirm very laggy behaviour on Matlab 2018b and Ubuntu 19.04. Has there been any workaround?

Same here, with Matlab R2017a under Linux Mint 19 on my Dell Laptop. This is absolutely horrible, so laggy that I cannot even use MATLAB, this worked so well under an older Linux Mint, I'm running crazy.
That's a shame, please fix ! I will not buy Matlab 2019 and install kernel 5.x (Linux Mint is stil on 4.x) just because of Mathworks devs !!
PS : any community workaround would appreciated.

The problem seems to be solved in R2019b... at least it does work for me on Ubuntu 19.04 and 10.10 with that release. They didn't seem to announce it (or I am not aware of it) but the issue seems no longer present in my case.

The issue seems to be with some package conflicts in Linux. My Liveeditor was running smoothly until I installed some MP4 codecs for screen recording. The entire Liveeditor is extremely slow to render.

Slow matlab edior problm is confirmed on my Ubuntu 22 machine.
R2021a does not have such lagging editor issue.
R2021b and R2022a has slow editor problem. I am going back to R2021a.
