Typing in the live editor is slow on Linux

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.

Confirmed on two computers running Kubuntu 18.04 with freshly installed MATLAB R2018b. As a result of the typing latency, the live editor is nearly unusable. This is especially annoying since our university currently has a course where all the answers must be submitted as live editor files (.mlx), and no other file formats are allowed.
The latency has been confirmed on the following hardware
  • Core i7-930, GTX 760, 24 GB RAM
  • Core i7-3517U, integrated graphics, 8 GB RAM
Edit: the bug is still present in R2019a and affects Kubuntu 19.04 as well.

This is a not really helpfull comment, but "me too".
There are two painful points in MATLAB on Linux: the Help Browser, which is slow to the point of inusability (I prefer online Help) and the Live Editor (to the point that I avoid using it by all means).

Same, I hope this is solved soon. I'm on 18.04 running R2019a, and it is terribly slow.

No way!
MathWorks have fixed this in R2019a Update 2.
Not only Live Editor now works fine, but also Help Browser runs very smooth.

Fixed using Linux v5.1.16 on Ubuntu 18.04 and MATLAB R2019a update 3.

With Linux 5.2 kernel Help Browser and Live Editor work fine, too.

Linux 19.10 Kernel 5.2 Matlab R2019a update4:
the Live Script editor seems fo be much more fluid (~90% compared to the reactivity of any other typing window, like what I am currently writing). Not perfect, but at least much more usable :)

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?

I found a work around for Mac a couple years ago (here), by installing Matlab kernel into Jupyther. Check references therein for Linux and Windows.
