Eike, good news! Problem solved. After struggling for a week with this issue,
the problem was with the xf86-video-intel driver. Since it defaults to DRI2, I
simply enabled DRI3 (--enable-dri3) and added on my xorg.conf:

Option "DRI" "3"

This results on the following:

[    56.746] (**) intel(0): Option "DRI" "3"
[    56.902] (II) intel(0): [DRI2] Setup complete
[    56.902] (II) intel(0): [DRI2]   DRI driver: i965
[    56.902] (II) intel(0): [DRI2]   VDPAU driver: va_gl
[    56.902] (II) intel(0): direct rendering: DRI2 DRI3 enabled
[    57.862] (II) GLX: Initialized DRI2 GL provider for screen 0

There's only 1 line which mentions DRI3 and I read somewhere the Intel driver
doesn't use DRI3 at all. Well, I'm using the latest git version
2.99.917-746-g169c74fa and it indeed does solve the issue (or maybe this is an
indirect consequence?). I don't know.

So I'll mark this bug as WORKSFORME. Maybe it helps someone using the same
setup.

Ps: and I tested it with UXA and SNA. The only way to solve it is enabling
DRI3.
