Try to enable EXA and play with Option "MigrationHeuristic" "greedy"I can confirm this solved my X problem. And it was really really a slow X. I added Option "AccelMethod" "EXA" Option "MigrationHeuristic" "greedy" in Section "Device".
This also fixes issues I had with very slow rendering on an Intel 865G card.
