Keyboard "Sticks" & System Acts Oddly After Long Idle

[mmxbass]

Late 2012 MacMini running Mountain Lion

After leaving the computer idle (several hours) after the screen has gone to sleep and such. Sometimes (not always) when I press some keys to wake the computer, things get weird:

First the keyboard gets "sticky". When I press a key, nothing happens, but when I HOLD a key in, it will rapid repeat that key after about a second. I thought this was odd behavior since that kind of "hold to repeat" behavior is common in PCs but doesn't seem to be the case in any recent Mac I've used.

The mouse is totally unaffected and acts totally normal.

-IF- the strange keyboard issue happens, many applications will get slow, crashy, refuse to quit, etc. If the issue doesn't happen, everything is fine.

Rebooting sorts things out but it's rather annoying.

NVRAM clear did not fix the issue.

I'm at a loss as to what to try next. Hoping for input.

Resetting SMC might help.

Resetting the System Management Controller - Support - Apple

SMC reset seems to have had no effect on the problem. I reset it last night and this morning I'm noticing no change.

Setting standby/autopoweroff/sleep/hibernatemode all to 0 in pmset has also not appeared to make any difference.

I've gone and done a Cmd+R boottime reinstall of OSX. We'll see if that helps. More suggestions while I wait though would be appreciated.

Seems to have had no effect. The problem still occurs.

Problem solved!

Cause: Running the "Flurry" screensaver for hours and hours on a dual-monitor setup.

Solution: Switch to "Message" screensaver and enjoy the hipstery grey-on-black.

Solution, don't use any screensaver, those were good for the old days with tube monitors.
Just let the display sleep, saves energy and prolongs the life of the GPU!

Probably a good idea in the general case. I used to just let the displays sleep before my monitors broke. Now I only sleep the displays after an hour because once the screens turn off, they won't come back on for 2-3 minutes.
