GTK+ change potentially breaks pan and zoom

Submitted by Jim Nelson

Description

As reported on the GTK developer's list:

https://mail.gnome.org/archives/gtk-devel-list/2014-June/msg00010.html

"With these changes, it is now illegal to call gdk_cairo_create outside of a begin_paint / end_paint."

This is done in one place in Shotwell: interactive zoom and pan.

I haven't had a chance to verify if this GTK change actually breaks zoom and pan, but reading over Jasper's explanation, I suspect it does (if zoom/pan even ever worked under Wayland).

Resolution: RESOLVED FIXED
