Description
When running gnome-photos, I'm getting many of these warnings from gnome-photos:
drawing failure for widget 'GtkImage': NULL pointer drawing failure for widget 'GtkOverlay': NULL pointer drawing failure for widget 'GtkBox': NULL pointer drawing failure for widget 'GtkAlignment': NULL pointer drawing failure for widget 'GtkRadioButton': NULL pointer drawing failure for widget 'PhotosToolFilterButton': NULL pointer drawing failure for widget 'GtkGrid': NULL pointer drawing failure for widget 'GtkRevealer': NULL pointer drawing failure for widget 'GtkGrid': NULL pointer drawing failure for widget 'GtkRevealer': NULL pointer drawing failure for widget 'PhotosEditPaletteRow': NULL pointer drawing failure for widget 'PhotosEditPalette': NULL pointer drawing failure for widget 'GtkViewport': NULL pointer drawing failure for widget 'GtkScrolledWindow': NULL pointer drawing failure for widget 'GtkRevealer': NULL pointer drawing failure for widget 'GtkGrid': NULL pointer drawing failure for widget 'PhotosPreviewView': NULL pointer drawing failure for widget 'GtkStack': NULL pointer drawing failure for widget 'GtkOverlay': NULL pointer drawing failure for widget 'PhotosEmbed': NULL pointer drawing failure for widget 'PhotosMainWindow': NULL pointer
Installed software versions: gtk3-3.22.17-2.fc26.x86_64 dleyna-renderer-0.5.0-6.fc26.x86_64 gnome-photos-3.24.2-1.fc26.x86_64 tracker-1.12.1-1.fc26.x86_64
Additional info: According to valgrind, this is not a memory corruption bug. I also observe that this only happens when clicking on "Filters". When I used gnome-photos for the first time, there were no filters previews. Now they are shown correctly.
