Hello,
Whenever I bring focus back to an App Designer window by clicking on a text box, my cursor appears and I can type in the text box, but if I click anywhere else on the screen again, my cursor disappears and I can't type at all. Keyboard shortcuts don't work either, but the mouse still works. The only way I can get keyboard input back is to click on a different window, such as Google Chrome, and click back on the textbox in App Designer. The apps made by the designer also have this problem.
It's fairly annoying and breaks my workflow, and I've considered running MATLAB in a Windows VM to get around the bug and to be able to finish my work faster. The normal MATLAB editor and command window works fine.
Running Ubuntu 22.04 using Wayland, window is running in XWayland mode.

This is a bug that's been around for a while and is probably here to stay. Unless you want to change your environment for the sake of MATLAB, there are various unsatisfactory workarounds.

You may also notice certain elements (e.g. dropdown menus in Add-On manager) won't respond to mouse clicks. In my experience, they actually do respond, but you only have a roughly 5% chance of the event being registered.

I have the same problem running Matlab 2023a. In other words, still no hint of a fix almost a year later.
According to the release notes by Mathworks, my configuration is compatible (Ubuntu 22.04, processores, etc.). Why are we paying for a product that does not work?
