It seems that this was a known issue with Go - can you please upgrade to at least 1.12.7 and try again?
golang/go#34935

@andydotxyz okay, thank you! I know that building option should point -ldflags "-w"，it means that I should rebuild fyne_demo.

[andydotxyz]

You should not need to worry about ldflags. Upgrading go and rebuilding fyne_demo should fix the issue

Please let us know if updating helped. No hurry but it's good to know if we have a Fyne issue here or not.
