Are you able to share the trace that causes the crash?

[wdscxsj]

Sure, please download it from here. The source code is from ardanlabs/gotraining. The crash basically happens when the cursor is moved around over the UI.

[dominikh]

Fixed, thanks.

[wdscxsj]

Thank you for the fix! But with the same input, clicking on goroutines may still cause panics:
