I thought it was 4096 bytes (1024 uchar32_t's), but yes, it is there. In particular, this is the maximum size of any particular protocol message that libwayland can transmit.

This is the first time I've heard of someone actually hitting the limit. Not that it hasn't happened before, I just don't remember it. Could you give a more concrete example of exactly what you're doing that hits it? How much surrounding text are you sending and how much is really needed? > I guess and hope that you guys already know how to handle this situation. > > 1.

Maybe, I’m totally misunderstood about the payload size. If you're misunderstanding something, it's probably the input_methods protocol. Unfortunately, my knowledge starts to break down here. I don't know too much about input methods but hopefully someone else will. I hope that was helpful. --Jason Ekstrand
