R2020b AppDesigner doesn't fill UiFigure completely with child

Hello everybody,

I noticed strange positioning behavior in the Matlab R2020b update. In contrast to the R2020a release, the complete UI figure is no longer filled in directly after starting the app, but only partially. I am demonstrating this using the "Pulse Generator" sample app without making any changes to the code. The red hatched area is undesirable and only occurs in the R2020b release. Why is that like this? Do we need to make any migrations to convert the app to R2020b?

On R2020b

On R2020a

The sample application is attached, but as I said, it is simply a randomly selected sample application that is suggested when creating a new document.

Thanks in advance!

Julian

I might have experienced something similar, but I am not sure if this is the solution. In your UIAxes, check the property group Position, PlotBoxAspectRatioMode and DataAspectRatioMode, try setting PlotBox property on 'auto', second one as well if it doesn't solve the issue.

There might be some issues when migrating apps that use GridLayout.

Thanks for your suggestion. Unfortunately, both values are already set to "auto" for me.

No problem with me here is the capture with R2020b

What is your monitor resolution setting?

[Julian Krebs]

Ok that looks fine. My monitor resolution is 1920x1080.

[Bruno Luong]

Odd I have the same screen resolution when I open your app.

[Bruno Luong]

Open on a different computer, il's till look fine.
