Is there something special I need to pay attention to when doing cross

It does indeed look like some step is missing. If I examine
/proc/<pid>/maps, I can see that the accessed memory address is
associated with the wrong render node:
Crash reading 0x7fffe4176000
7fffe4176000-7fffe4400000 rw-s 100602000 00:06 500
/dev/dri/renderD128
The X server is using renderD128, but the client is using renderD129.
This works with other X servers, so I assume there is some way to
resolve this. But where do I start looking?
The fd I'm getting is a DMA-BUF fd, I assume? I can't find many ioctls
for that. But that's also all I'm getting, so there must be something
I'm supposed to do with that fd?
Help! :/
