Whenever one of the KDE screensavers runs (in my case, KDE Asciiquarium), after the screensaver is done running (in my case with no password), the process 'kdeasciiquarium' stays running and consumes about 30% of the CPU. It won't die unless I kill it manually. I have been using Kubuntu since version 12.04 and have not seen this problem until I upgraded to version 13.10. Reproducible: Always Steps to Reproduce: 1. Have screensaver KDE Asciiquarium set to run (in my case after 10 minutes). I have no password required. 2. Wait time required for screensaver to turn on. 3. After a minute or two, hit a key to turn off the screensaver. Note the process still running consuming a lot of CPU. Actual Results: The screen saver process stays running, consuming 30% of my CPU. Expected Results: The screensaver process should be killed and not hoggingthe CPU. I have only seen this going on Kubuntu 13.10. This is a 5-ish year old Toshiba Satellite laptop with only Kubuntu on it.
Note, I have seen this defect below and while I think it's related, I am not sure it's the same issue as the "blank" screen saver works for me and this bug has no mention of lots of CPU consumption. https://bugs.kde.org/show_bug.cgi?id=224200

The screensaver processes that keep running do of course consume the CPU, how much depends on the particular screen saver obviously. As to why it doesn't happen with _all_ screen savers (it even seems to happen with different ones on different systems), I am not sure really. But I do have a patch ready that fixes the issue for me. (I haven't seen any left-over screen saver processes in 2 weeks now... ;-) ) *** This bug has been marked as a duplicate of bug 224200 ***
