I experience the same behaviour. The slgui window shows up all black with a few dark grey boxes, then stays that way. stdout shows:
slgui: our URL is osc.udp://localhost.localdomain:19596/ I/O warning : failed to load external entity "/home/roger/.sooperlooper/gui_config.xml" Error loading config at /home/roger/.sooperlooper/gui_config.xml! execing: 'sooperlooper -q -U osc.udp://localhost.localdomain:19596/ -p 9951 -l 1 -c 2 -t 40 -m "/home/roger/.sooperlooper/default_midi.slb"' slgui: spawned new engine slgui: remote looper is at osc.udp://localhost.localdomain:9951/ version=1.0.8c loopcount=1 sooperlooper warning: could not open for reading: /home/roger/.sooperlooper/default_midi.slb -- slgui makes Xorg use all the cpu https://launchpad.net/bugs/72452 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
