As Robert and Stephen have independently observed, this is a Heisenbug.
It's due to to the fact that WM notifications about new frame sizes may
be processed earlier or later.  I tried to fix that behavior in commit
a190b4cfd8b6f42a91678ac7292e1cceccd168e7 by having adjust_frame_size
pick up such notifications on the fly and am closing this bug.

Thanks, martin
