It's been like this for as long as we've been parsing frame extents.
The warning message was wrong and printed the already-truncated value
twice, that's now fixed:
https://xpra.org/trac/changeset/20535

More details here:
https://xpra.org/trac/ticket/1279

For the record, since the compiz code looked correct, I also suspected a
bug in xpra but I couldn't find one so I even tried to query the frame
extents using "xprop" and found the same invalid values that way.

Cheers,
Antoine
