App Designer - App window not fully displayed on transition to 2024A

Hi,

I had a MATLAB GUI coded with App Designer and working under 2022A as you can see in window screengrab in image 1 below. It remains working and may be run from within the App Designer of 2023A.

I have now reopened the GUI in App Designer under 2024A, I get a warning stating that it was created under 2022A, and my app's main window, while fully displayed in the Designer, is not fully displayed when I run from within the Designer as seen in image 2 below. The tabs, File dropdown, and Help dropdown are not showing.

Can someone please help me resolve this issue.

Thanks

Is this issue sporadic, or does it occur consistently?

Hi Naga,

The issue is persistent. I have opend and closed MATLAB multiple times and now restarted my PC and the issue has persisted.

Are you able to share the code with us?

[Shaun Forth]

And if I package the App using R2023A and then install into R2024A the problem still exists. But if I install into R2023A then it works fine. I'm thinking this must be a bug in R2024A.

Hi Taylor,

I can zip it up. There are quite a few files and folders! It is by no means a minimal demonstration of the behaviour. I was wondering if others had experienced such behaviour? I'll sort out the upload and test it installs (but doesn't work properly!).

Hi Taylor,

My zip file called Matlab.zip is too large to upload to MATLAB Answers - you can downlaod it from my University's drop-off server here.

Within Matlab.zip there is a folder Matlab.

1. Unzip the file and add the subfolder Matlab and all its subfolders to your path.
2. Go to subfolder ProSAirPostProcess and open ProSAirPostProcess.mlapp in the App Designer of R2024A.
3. Run the App and you should get the App opening as for my Image 2 above.
4. Now open ProSAirPostProcess.mlapp in the App Designer of R2023A
5. Try to Run the App and you should get the App opening correctly as for my image 1 above.

Hey Shaun, I'm unable to reproduce the issue in R2024a.

Hi @Shaun Forth,

I think that the issue might be because of the Windows text scaling setting. The following workaround might be helpful in resolving the issue that you are facing.

1. Go to Windows Start and search for "Make text size bigger".

2. Open the setting for "make text size bigger".

3. Set the text size to "100%" and click on "Apply".

Or, you may want to upgrade MATLAB version to R2024b.

Dear Sachin,

Thanks so much, that has resolved the issue.

You mention upgrading to MATLAB R2024b. Has this issue been resolved in that release?

Kind regards and thanks again.

Shaun
