I run the following codes in the same PC with different versions of MATLAB.
And the rendering results of the LaTeX equation are different.
x = 1:0.1:10;
y = sin(x);
figure;
plot(x,y)
xlabel('$\tilde{x}$','Interpreter','latex')
ylabel('$\tilde{y}$','Interpreter','latex')
In MATLAB R2020b, I obtain the proper format of \tilde{}:
However, the format in R2025b is weird:
How can I obtain the proper result of \tilde (like in R2020b) in R2025b?

(Because I missed it initially:
The difference is that before the tilde over the x was smaller than the x and was centered over the x, but now the tilde is larger and is not centered over the x.)

Ran in:
That appears to be what the interpreter now defines as '\tilde'. I thought it might be defaulting to '\widetilde' , however that behaves as I would expect it to when I did that experiment.
x = 1:0.1:10;
y = sin(x);
figure;
plot(x,y)
xlabel('$\widetilde{x}$','Interpreter','latex')
ylabel('$\tilde{y}$','Interpreter','latex')

I suggest that you Contact Support, and perhaps the LaTeX authors.

Ran in:
I tested. Even \hat{x} or is now not centered over the x.
figure;
xlabel('$\hat{x}$', 'Interpreter', 'latex')

It looks like graphics LaTeX renderer has changed. It is now producing something that looks similar to what is shown in the MATLAB editor:
The tilde is centered, but in a different sense than before. It is centered over the entire horizontal extent of the character. It appears to be uncentered because of the slanted italic font. Previously it was centered over the top of the character. Compare with \tilde{\text{x}}:
I agree with Star Strider's recommendation to contact MathWorks support. It would be useful to let them know that you regard this particular math rendering as incorrect.
