I may have found the culprit. I'm wondering if somebody else can confirm for me.
Now I'm not sure if this piece of software is the cause or simply a way to trigger something in the OS. There seems to be a particular set of things you have to do to get it to trigger. I've been able to do it reliably now about five times in a row tonight. I never really put two and two together before because I was never really doing all these things simultaneously all the time.
The cause (or a cause) seems to be Pocket Player by Conduits. I listen to music so often, that like I said, I never really put it all together. Also, it doesn't seem that PocketPlayer has to even being playing when the slow-down occurs, just open and having had played in the past.
Here are the steps to reliably trigger the slow down on my phone. I'd love to see some confirmation from somebody else.
1. Enable bluetooth (it's not important that you play through A2DP, and the slowdown can happen without bluetooth, but this seems to speed it up for some reason)
2. Run pocket player
3. Enable a CPU intensive visualization (eg, NOT album artwork -- I've been using Randomization)
4. Play a shoutcast stream (in case the stream might be important, I've been using Energy 98 which is

5. Turn the visualization on.
6. Connect your device to AC power.
7. Keep the screen on (don't let it sleep -- PP has an option for this or you can disable all screen dim/screen off in WM power settings)
8. Wait a couple hours
9. Exit Pocket Player and open an app that uses a lot of GDI drawing, like Pocket Outlook Email or Total Commander. The apps should be running incredibly slow. To confirm the slow-down, soft reset and compare the speed after the reset.
Doing this, I've made the device slow down five times tonight. For the previous three days, I've been using SPB Radio to play my audio streams with NO slow down. So I'm pretty sure this may be the culprit.
I hope somebody can confirm. Please make sure you let your device run long enough (give it a few hours at least, or let it run overnight to be really sure). I ran my device on mute so I wasn't bothered by the music while I did something else.
