This is possibly happening in Linux too (not sure), but I have an app compiled with 2019 R3 for the Raspberry where CheckBoxes are broken.
Create a new app, add a CheckBox in the window, set the ‘Visual State’ to ‘Checked’ and then run on the Pi. The CheckBox is not checked.
Re-open the project in Xojo… now you can’t change the CheckBox state… you have to select/deselect/reselect the CheckBox to get access to the visual state popup menu…
Now you’d think you ‘fixed it’… save/compile again… still does not work when ran on the Pi (not checked).
(does not happen if compiled on macOS)
Back to 2019 R1.1 for me… possibly for a long time.
