After updating to macOS Tahoe, my Matlab 2024b text in GUI becomes super blurry

The GUI texts in both Matlab R2023a and R2024b were sharp and clear in macOS 15.7. But after I updated my MacBook Pro 2020 M1 to macOS 26.0, the texts in both Matlab versions were blurry and I have not found a way to make them sharp. I have the reasons to keep the R2023a and R2024b so please help. Thanks.

We've done some analysis and think the issue is due to the combination of Java 8, macOS 26, and Apple Silicon. We haven't fully validated yet, but recommend that anybody having this issue verify that they are using Java 11 or newer.
This page gives system requirements and provides a link to install Java 11: MATLAB on Apple Silicon Macs
You can use the matlab_jenv, or jenv, command to configure MATLAB to use the newer JRE version.

Thank you very much for the solution!
I can confirm that changing to Java 11 solves the problem on macOS 26 on an apple silicon (M2). But that the problem exists also on Intel macs. Downloading Java 11 for Intel https://corretto.aws/downloads/latest/amazon-corretto-11-x64-macos-jdk.pkg also solves the problem there.

You can verify your current Java version with jenv. This page gives system requirements and provides a link to install Java 11:

We believe this is only an issue for releases 24b and earlier. We haven't seen or heard of issues with 25a and 25b.

I have installed the Java 11 through the provided link but how do I know it is running? or are there any adjustments I need to make after the fact.

I have confirmed that R2025b looks fine in Tahoe 26.0.1 while R2024a is blurry. Mac users should strongly consider upgrading to R2025a or later, with the understanding that there will be signfiicant pain transitioning legacy interrfaces from Java to JavaScript.
