This problem appears at least 2 or 3 times a week, and until the program is restarted, there is nothing I can do in the tool to reduce the cpu usage. My first idea was to check if the current script was looping, this was not the case. The issue always appears while the computer is not in use (idle), usually on the night.
Does anyone here get the same issue ?
I made some samples of the key profiler while eating cpu cycles, if a dev would like to get it

I've reported this bug, and run out process samples from my macbook. The conditions for this appear to be: Waking the Mac from sleep, without a G-Series keyboard plugged in, and after a couple minutes, sometimes the LCD Manager application will proceed to run rampant, taking task manager along for the ride.
At this point, quitting LCD Manager and restarting it appears to resolve the issue. We're working on a software solution to this as well.

That matches my experience very closely - I have my G15 connected to my MBP - and frequently disconnect / sleep - I'd got as far as realising that disconnection had something to do with it - but hadn't got as far as realising that sleeping was also a factor.

That's the way I get it to occur: I have a G-Series device plugged in, remove it, and put the system to sleep, and then sometimes 5-15 minutes after waking, I realize that the fans are spinning fans too fast.
I've extracted sample processes using activity monitor of LCD Manager, but I can't extract from kernel task (Activity monitor wont allow it for obvious security reasons. Maybe if I sudo'd in through the CLI I could extract that, but I'll leave that to the actual engineers to do )
That being said, we have some new Mac releases on the roadmap, but I haven't followed up on my bug filing on this in a while, so I'm not sure the current status...

Thanks for your feedbacks.
Unfortunatelly, this is not related to the LCDManager app, but really to the G-Series Key profiler. I completely disabled the LCDManager for the issue you are refering to
About the issue I get, the scenario is not the same, but appears to be :
1 - The G13 keyboard is always plugged in, since the initial startup of the mac.
2 - I let the mac alone, and after some time, I hear the vents
Another scenario highlight those days, this even happens when I quit a game (I don't thing it happens when the game is running, or I should see things stutter, but that don't seems to be the case).
If any of you would like to get the samples, I'll be happy to send them to whatever mail. samples show a lot of occurences of :
2311 Thread_1008236 2311 thread_start 2311 _pthread_start 2311 DeviceManager:nSetUpForDeviceNotification(void*) 2311 HIDDeviceManager:etUpForDeviceNotification() 2311 CFRunLoopRun 2311 CFRunLoopRunSpecific 2311 __CFRunLoopRun 2311 mach_msg 2311 mach_msg_trap
after another (too long to be sent here).
thanks in advance

I have the same issue. I just disable LCD manager ongoing as it is routinely causing the Mac Pro early 2009 to run too hot. I would rather replace teh keyboard than the Mac Pro!

I have the same issue. I daily have to kill the process for the LCD manager and quit the G Series profiler. I have a G19 and a G13.
After I quit them and restart the programs the will be fine again for about a day.

So I see they said they were working on this in 2006, it is still happening, on my new imac, 2011? is there ever going to be a day that Logitech supports its mac software a little better? I feel like if it is always going to be this way I should be more loyal to another maker that supports its hardware a little better. I love the Logitech hardware, I own a lot of it, but it just isn't supported for **bleep**, send this to corporate and tell them to contact me, i'd love to sit down and teach them how to get more apple customers buying their hardware, I just can't recommend to my clients any of this hardware because it is buggy like a windows OS, and that is why mac users use mac, because it isn't windows, it works with very few bugs, can i get someone to direct me to someone in PR who might be able to move me up the chain to get some brances rattled on high to pay you guys more to support your software better? I don't blame you programmers, I blame corporate. who do I talk to?

I'm having the same issue. Fans were going at full pelt on my 2009 iMac quad i7, the G13 isn't plugged in, found LCDManager consuming 40%+ of CPU. I killed LCDManager but from the comments on here fully expect it to happen again. Last software update in August last year? It'd be nice to see an update with a fix, but I'm surprised there haven't even been releases with extra game profiles.

I'm having similar issues with my Macbook Air (c2d) on 10.7.2. Randomly, LCD Manager will eat up most of my CPU % and I have to force close it. Also, when I attach or detach the keyboard, my CPU shoots to 100% for a minute while it 'detects' the keyboard.
The GamePanel software for mac is over a year old and seems neglected. Please support your Mac users.
