Real time movements during drawing

I wrote an App using Matlab2021a that graphically illustrates real time linear combination of vectors by means of sliders working as the linear combination factors. It worked fine. When I upgrade my Matlab to 2022a, the real time effect was gone. The drawing appears only when I stop moving de sliders. Does anyone know what possibly is going wrong?

can you show us the code? how did you implement the "real time" callback? normally i would create a listener using addlistener() with the 'PreSet' option

Hey Marco,
I understand that you wrote an App in MATLAB r2021a using “uislider”. You used “ValueChangingFcn” callback to get the real-time visualization of your app. The effect was no longer present after updating MATLAB to r2022a. I tried to open the link present in the comments, but the code file is not accessible.
Please check if the “uislider” has only the “ValueChangingFcn” as the callback. You can search for the callbacks you have added. Refer to the following:
There is an example present in the documentation using “ValueChangingFcn” callback for the release r2022a which works fine. I have tested the example at my end. You can have a look at the documentation for the same here:
You can test out the example to check the callback using the following command:
openExample('matlab/SimpleAppWithCallbackExample')
To get a better idea, please share the code files used for the app.
Hope this helps!
