Thanks for this but it still doesn't seem to get the right line. Adding a go statement before the first w.Resize() call in fyne_demo gives me this:

2025/01/26 20:49:04 *** Error in Fyne call thread, this should have been called in fyne.Do[AndWait] ***
2025/01/26 20:49:04   From: /var/home/jacob/git/fyne/internal/driver/glfw/window.go:242

When testing inside the fyne codebase it is not possible to deduce where the line between library and app are.
Try with one of your apps or anything in a different repo...
