Right, which is why I'm saying we don't need more backtraces right now.

As I said in comment 15, the question is how ppriv->notify_on_damage ends up
being TRUE in ms_dirty_update. The only way I can see that being the case is if
 msRequestSharedPixmapNotifyDamage was called before, but xf86-video-amdgpu
doesn't have any code calling the RequestSharedPixmapNotifyDamage hook.

None of the questions in comment 27 are related to remote access or gdb.
