The file xpsfts-a4/fts_44xx.xps regularly shows spurious rendering differences in the cluster regressions. I've removed the file from the regular test set to cut down on noise since this has been a long-standing issue. It should be restored when this bug is resolved.
Raising priority since this affects regression results.
