I have been trying other things too, disabling Composite solves the
visual issues, but not screenshots. xcompmgr does not want to launch
and returns 1, of course.
My logs have been reporting for some time that both DRI and DRI2 are
being loaded, but at the same time it shows:
---8<---
(II) AIGLX: Screen 0 is not DRI2 capable
--->8---
And xdpyinfo shows DRI2 and XFree86-DRI. A bit confusing.

I know, but no idea how that applies. To make it clear, the "weird 2D"
window is below the others. I can get screenshots of it if uncovered,
and I can get screenshots of other 2D windows. When a 2D window is
placed over the "funny" one, then the overlapping pixels appear black
in captures, while monitor shows the contents of all windows fine.
3D case is the same... it is like if some kind of "censor" went over
pixels looking for where 3D or the "weird 2D" are behind others and
set black the pixels delivered to the capture process. What I expected
is to see whatever is on top, thus preserving (or not) things that are
behind should not matter. See attached screenshot and mockup of what
it should show.
