Description:

gamescope can not be upgraded to 3.11.36-1 or installed because it depends on libliftoff but wants to install a file owned by libliftoff.

libliftoff owns the file /usr/include/libliftoff.h
gamescope tries to install this file. Pacman fails to commit transaction because of conflicting files.

Additional info:
