Describe the bug

On Android v9 (moto g6) with fyne v2.3.0, I pop up an OpenFileDialog and close it, and then the main app window fails to get re-drawn (appears empty/blank) and reports:

01-05 22:25:17.390 6458 6484 I Fyne : app: failed to swap buffers (EGL_BAD_SURFACE) 01-05 22:25:17.400 6458 6484 I Fyne : app: failed to swap buffers (EGL_BAD_SURFACE)

Additional Information

(I vaguely remember a similar problem a few years ago where iterating the surfaces gave an unusable one first, and the fix was to find another one that worked! Sorry I have no further info to hand)

Can you please confirm whether or not you see the same behaviour with the fyne_demo app which uses the file pickers too.

no, the fyne_demo seems to work fine (pun intended) :)

You shouldn't ask the UI to show things on "Started". What happens if you move this to "Focused" instead (yes you'll need a little more code to avoid doing it every time the app comes to foreground).
