Found a bug in maxcoin-qt g047adead I have never experienced before: when I change desktop away and back to where maxcoin-qt was, it has disappeared from view!
But it's still running and writing happily to log files. Does not show up in alt-tab list, either.

Fedora 20
qt-x11-4.8.5-15.fc20.x86_64
openbox-3.5.2-2.fc20
xorg-x11-server-Xorg-1.14.4-5.fc20.x86_64

BTW. would anybody be interested in my patch to cpuminer-1gh, optimizing the keccak (3400 to 8100 khash/s on Core i5-2600K)? I guess nobody would care (40 W for 8 Mhash/s), but I was just testing for fun
