as the title suggests, i've upgraded one machine to -currrent (as of 2012-02-22) and find my windows are lacking the mover bar. The other window decorations are present (buttons). Truth be told, since mesa was part of the package I took the opportunity to upgrade the nvidia binary driver as well (NVIDIA-Linux-x86_64-310.32.run).
I'm on 64bit architecture, XFCE, no compositing, GF 560 Ti.
I am still in the process of varying parameters. As part of that I have "upgraded" cairo, fontconfig and freetype to -current, too, which means i have lost lcdfilter and i am back to ugly fonts
Anyway, if anybody has an idea please let me know.
