I believe that was a bug fixed in Qt 5.13(ish).  See Qt
commit 425c59783c or the original bug report QTBUG-73911
(which does not directly mention the refresh rate in the report,
just in the discussion, but the resolution was to return a proper
real value for the refresh rate).

I am not a decider, but none from me (as I have been
building with RandR support for quite some time), and
the MythTV packaging repo requires the xrandr libraries
for the usual suspects, so I expect no changes in results
for those using the normal processes.

I suppose in theory one should move the ansible line
from the "optional" to the "essential" group, but that is
mostly just a minor nit in grouping in the playbook, and
does not impact what is installed (and I think at least
one of the essential group items (hdhomerun) is technically
optional, so the list is not entirely grouped correctly
today).
