same here (180.xx unusable).
maybe this has something to do with:
iirc the problem is:
[mi] EQ overflowing. The server is probably stuck in an infinite loop.
[mi] mieqEnequeue: out-of-order valuator event; dropping.
(disabling xinerama doesn't fix this for me)
for me this also happens with 177.82 but only causes a temporary freeze (and no corruption) (also annoying).
(bug report created with 177.82, can create one with 180.xx if needed)
