If this happened for a build of master in between commits

c0af83b6ccf2dab9a515dd7f52eb9d4500275ae3

and

2fa19cc5510cdbf00c54991a9959be984dd99fbe

it would imply that inhibiting double buffering is also needed even if
it did not cause problems like those from bug#28589.  But apparently you
built from the release branch.  So I'm slightly confused.
