Slicer hangs Debian Sid
The new slicer 1.42b2 hangs my Debian-Sid Laptop completely, only the power switch helped. Especially I observed it in the sliced graphics, checking layers. A complete freeze of Debian Sid occurs seldom, but the because keyboard was out of use with this, a revival was only possible via power break.
Any clues for me?

Was it also unresponsive to SysRQ key interrupts or Ctrl+Alt+Backspace? Most likely your graphics driver bugged out and froze the display. IIRC it had some GL improvements; you may need to disable that on your particular system. I believe there is a preference setting related to the graphics drivers.
SysRQ+r forces the keyboard back to low-level control in the case X has hung and is no longer responding to it; from there you can usually kill X or switch back to a TTY and kill/restart any problematic processes.

FYI: before hard-powering off a linux system it's always worth "raising skinny elephants"... this refers to a magic key sequence that attempts to safely kill running processes and flush to disk, minimizing any risk of filesystem corruption.
The mnemonic to remember it is "Raising Skinny Elephants Is So Utterly Boring". Hold Alt+SysRq and then type the letters R,S,E,I,S,U, and B.
