The bugtracker seems to be taking a nap, omgubuntu have a summary of the "bug" here: <a href="http://www.omgubuntu.co.uk/2017/03/xfce-wallpaper-cat-bug" rel="nofollow">http://www.omgubuntu.co.uk/2017/03/xfce-wallpaper-cat-bug</a>
Very strange. Neither of my cats have ever paid the slightest bit of attention to the contents of any screen on any device I own. Yet I know people whose cats like to watch television, so there's some thing going on where some cats see screen images as significant and others don't. I should go looking for info on that!<p>In any case, I don't see how this is XFCE's problem. Just change the wallpaper.
I remember my early days of computers (not as old as some folks here, I know) when there was an intense debate on whether a software could cause damage to some hardware.<p>I remember programing a small .asm that would move the head of a floppy to a farther point and it stoped working. Probably not all models would fail, but one particular brand did.<p>Then a intense debate followed that I was wrong. Never talked about it again.<p>Fast-forward, now we have news that nuclear programs had malfunctions caused by cyber-attacks. Ok, not exactly the same "software doesn't damage hardware" we talked back then, but...<p>I'm willing to consider that using software to make some catware cause damages to the hardware should be acceptable too :D
