Bug 99899

wayland 1.12.0 tests pass on all architectures that Fedora builds for, but 1.13.0 fails one test on ppc64. They pass on all other architectures, including ppc64le. Here's the failing test-suite.log for the ppc64 build. Full build logs are available on https://koji.fedoraproject.org/koji/taskinfo?taskID=17988030 (short lived link):
