I had a bit more time to play with this. I wrote the simplest possible reproducer that still exhibits this behavior (ie, without all the Quickly boilerplate). It's only 34 lines long, and so far it leads me to believe that this is actually an issue with the vbox packing.
I've yet to decide if this is actually a bug per se, or if the behavior has simply changed and code will need to be rewritten to reflect the changes. ** Attachment added: "Bare minimum code necessary to reproduce the issue." https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1036455/+attachment/3261502/+files/simplest_reproducer.py -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1036455 Title: GTK Rendering Issue (potentially a ScrolledWindow problem) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1036455/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
