How low speed is that?

They are only waiting for 50 ms before timing out, I raised it
to 100ms in the -next kernel. I'm still suspicious about this
even though I think you said this was not the problem.

For a command mode panel in LP mode it will nevertheless
be more than 100ms for sure, the update is visible to the
naked eye.

Raise it to 10000 ms or something and see what happens.
