This could very well be the case, this is built against cm11. Which version of CM did you use when it worked? EDIT: Regarding sfdroid and input, can someone try running this command: # while true; do if [ -f /tmp/sfdroid/have_focus ]; then echo "focus"; else echo "no focus"; fi; sleep 1; done and minimizing/maximizing sfdroid while this is running? It should print "focus" if the window is maximized and "no focus" otherwise, if it does not switch between "focus" and "no focus" we know where the issue lies. But i would be suprised if this is the problem, because on my Jolla the file gets created/deleted correctly. But BluesLee said input works when restarting sfdroid which would indicate that there really is something wrong with file creation when focus is gained.
