scrolling through many photos breaks the view

Bug #1606491 reported by Michael Zanetti on 2016-07-26
This bug affects 7 people
Affects Status Importance Assigned to Milestone
Fix Released
shotwell (Ubuntu)

Bug Description

* Impact
Sometimes when scrolling in a photo collection the view becomes white and shotwell needs to be restarted

* Test case
No specific steps, but it seems that scrolling on a big collection sometime trigger the issue. It seems more likely on a 4k display. Scroll on a big collection, it should keep working

* Regression potential
Nothing special, make sure that scrolling works without visual artifacts.


Having some couple of thousand pictures in the photo library, scrolling through them with shotwell makes the picture view just go white. Shotwell needs to be restarted in order to recover. See attached video.

This is printed in the log:

(shotwell:9274): Gtk-WARNING **: drawing failure for widget `CheckerboardLayout': out of memory

(shotwell:9274): Gtk-WARNING **: drawing failure for widget `GtkViewport': out of memory

I have verified that the machine is not out of memory. It has 8GB of RAM and another 8GB of swap space which is not even touched yet.
