Describe the bug:

When CenterOnScreen() is called it typically works, however it will reliably crash if called in a separate place of the code.

I haven't identified the reason why this crashes yet, and other places in the code work fine, but I am opening this issue for tracking and in case someone else has information.

To Reproduce:

Steps to reproduce the behaviour: Unknown

Example code:

        canvas.Refresh(s.output)
        s.w.Resize(fyne.Size{s.width, s.height})
        s.w.CenterOnScreen()

Device (please complete the following information):

  • OS: MacOS
  • Version: 10.15.7
  • Go version: 1.15.3
  • Fyne version: 1.4.0

Output

Output

The following example will trigger the crash:

package main

import (
        "time"

        "fyne.io/fyne"
        "fyne.io/fyne/app"
)

func main() {
        a := app.NewWithID("com.example.crash")
        w := a.NewWindow("Crash test")
        w.Resize(fyne.Size{Width: 320, Height: 200})
        w.CenterOnScreen()
        w.Show()

        go func() {
                time.Sleep(3*time.Second)
                w.Resize(fyne.Size{Width: 640, Height: 300})
                w.CenterOnScreen()
        }()

        a.Run()
}
