I found this code in glz_encoder.c in spice-server:
static inline void encode_64(Encoder *encoder, uint64_t word)
{
encode_32(encoder, (uint32_t)(word >> 32));
encode_32(encoder, (uint32_t)(word & 0xffffff)); // <----- is it wrong? 0xffffff should be deleted

Is normal that dist is less then id.
The id, as far as I know, is incremented from 0 and is a 64 bit, not
supposed to overflow, is truncated to get the slot and should not be a
problem. The same check "w->images[slot]->hdr.id == id - dist" is done in
wait_for_image which should return TRUE and so "image && image->hdr.id == wait->id"
should be true.
Could be that g_coroutine_condition_wait returned FALSE? I think that just calling
SPICE_DEBUG is a bug.
