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
In cross-GPU combinations where it works, I'm seeing this map instead:
7fffef30e000-7fffef408000 rw-s 100056000 00:0b 533
