Could be a regression, I don't remember seeing those /before/ and the
downstream bugs about black icons are recent as well.

And there've been some glamor changes in the xserver as well, so it oculd be
/something/ in glamor has changed and doesn't play well with the driver.

Yes, that makes me think of that as well, could explain the black icons being
reported downstream.

Good, so I'll rebuild with "--enable-debug" and see what I get.
