Which version of TouchGFX Designer do you use ? Do you mean that you're using the simulator and it crashes ? Do you reproduce is bug with a real board (and if yes, which one) ?
I use TouchGFX Designer v. 4.18.1. When I have multiple screens with multiple widgets and have them opened, the Designer freezes when I scroll down to the bottom, and once the designer is minimized, it does not open again. It happens with the designer itself while I am working on projects.
I'm sorry I did not understand your third question.
Unfortunately, I am not at liberty to share my project at the moment.
Ok I understand, maybe can you share it with one of our FAE (field application engineer) in private ?
I invite you to fill this form for a specific help.
We will need at least the log file of your TouchGFX Designer to identify the bug (you can find it in : C:\Users\YOU_USER_NAME\AppData\Roaming\TouchGFX-4.18.1\TouchGFXDesigner.log).
Unfortunately we couldn't achieved to reproduce the bug on our side. Could you share with us your project ? A video of the bug would be nice too if possible :)
