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.
