Design view doesn't match how the actual app looks like

I'm trying to design an app with the MATLAB App Designer and I'm falling at the first hurdle - laying out the components. I tried setting their positions and sizes manually and that didn't work, so I decided to go with something simpler and use the grid layout instead. Here's how some components look like in Design view:

And here's how the actual app looks like:

For some reason the buttons and edit fields got stretched out and are now interfering with each other and the "Drop Down"/"Edit Field" labels have moved. Does anyone know how to make my app actually look the way it looks in Design view?

You'll have to point out what you think looks different -- to me, the two images look identical???

In Design view the button and edit fields look good and are evenly spaced out:

In the actual app, they are stretched out and there's no space between them:

I don't have R2024b installed so can't check there; I don't see anything untoward in R2022b here...

I'd guess upload a minimal UI mlapp file that demonstrates the problem on your end so folks here can see if that is reproduced on other systems or is something unique to your graphics drivers or system....

I'll try installing R2022b and will get back to you with results

Installed R2022b and it worked like a charm, thanks :)

Report it as a bug.

Hi @Arkadiusz,

I tried this in R2024b and i don't see any issues with the stretching of fields. Can you share the .MLAPP files you were working on?
