I still get issues when running MATLAB r2008 under Hard (32-bit and 64-bit). I've tried the sed thing, the SLOPPY_LOCK export and have all the updates installed as of today.

Basically, matlab over UNIX sockets (the default, DISPLAY=:0.0) seems fine, but over TCP sockets (DISPLAY=localhost:0) is is usably slow. Even older versions of matlab have issues. Same applies to Maple and any other odd Java programs I have. I need the TCP sockets because I'm deploying (well, stalled until this is sorted) Ubuntu on servers here which I need X11-over-TCP for.

Why can't we just remove the XCB infection/bridge layer from libX11 and revert it to the stock libX11 module? Let old libX11 programs use that, and new ones use XCB.

Thanks!
