Describe the bug

While trying to fix my pull request #6234, I noticed that a call to obj.MinSize() breaks TestRender (in driver/software/render_test.go:17). This isn't an issue in any real app but it surprises me and might be an indicator that something is broken. (Or maybe the test is wrong.)

How to reproduce

1. Apply this patch:

diff --git a/driver/software/render.go b/driver/software/render.go
index 2a22d43db..3fb6d3f57 100644
--- a/driver/software/render.go
+++ b/driver/software/render.go
@@ -27,5 +27,6 @@ func Render(obj fyne.CanvasObject, t fyne.Theme) image.Image {
        c.SetContent(obj)

        app.ApplyThemeTo(obj, c)
+       obj.MinSize() // this breaks TestRender
        return c.Capture()
 }

2. Run: go test -v -test.run 'TestRender$' ./driver/software

Output:

Update: It turns out, this wasn't an issue before my own PR #6231 was merged. Maybe there is just a Refresh call missing somewhere.
Update 2: When I call obj.Refresh() after obj.MinSize() the test passes. I'm not sure if a Refresh call should be required here.
