simulink menu icons missing?

I am experiencing a persistent issue with the Simulink interface across multiple MATLAB releases (2022b, 2023b, and 2024b). The problem is that the menu items are not displaying properly. I have been troubleshooting this for a while but have not found a solution. Has anyone else encountered this, and could you offer any advice on how to resolve it?

Hi @haodong chen,

I understand you’re experiencing issues with Simulink menu items not displaying properly across MATLAB releases 2022b, 2023b, and 2024b. This has been reported by other users as well (MathWorks, 2023). You can try the following steps:

Restore Default Path and Rehash Toolbox Cache



restoredefaultpath;
rehash toolboxcache;


This refreshes the toolbox cache and restores default paths (MathWorks, 2023a).

Refresh Simulink Customizations


sl_refresh_customizations;


This rebuilds Simulink menus and toolbars (MathWorks, 2023b).

Check High-DPI Display Settings : Adjust display scaling or DPI settings if using a high-resolution monitor (MathWorks, 2023c).

Reinstall MATLAB: If the above steps don’t resolve the issue, reinstall MATLAB.

If the problem persists after these steps, I recommend contacting MathWorks Support directly—they can provide guidance specific to your system and MATLAB version.
