This thread has been quiet of late and seems to be an annoyance that a real
problem.
I would like to suggest that it might belong on x11@ rather than current@.
I see the same issue on stable and first saw it in late March after the
MFC of r280369 which incorporated r277487, r277959, r278146-278148,
r278152 and r278159.These are all older than the commits suggested. r277487
was the primary commit to head.
I reported this to x11@ back on April 1, but when I went a day with no
errors, I sent a note that it was transient and had disappeared on April 9.
Clearly I was too quick on the draw as the messages reappeared in a day or
two, but I never got around to following up.
