Those of you living on the bleeding edge (hello Arch Linux users!) might have noticed that the new xcb-util library breaks mcwm. David Jacobs presented me with this patch:
I haven't found the time to test it myself but perhaps it can be useful to some of you.
Renato Botelho do Couto, garga@, is importing the new xcb-util to FreeBSD ports and said he is going to add David's patch to the mcwm port as well.
When I'm back from 28C3 @ Berlin I'll have a closer look at all this.
If you're also at the 28C3, feel free to get in touch. I'm at 95445 on the conference phone network.
