[thx1200]

I have a problem that has persisted through three physical Sprint Touch Pros (had to replace mine twice for unrelated reasons), three different ROMs, and two different radios. I've done the "don't install anything and see if it still happens" thing. It does. I've tried every tweak I can find. I've tried disabling multiple services, using the default dialer, disabling TF3D, and many, many, MANY hard resets, etc..etc.. basically all the stuff anybody ever tells you to do when you are having a weird problem. I just had to get that out of the way. lol.

Here's the problem. After some time (it varies -- could be as short as a few hours, or as long as a week), all GDI graphics operations and standard windows controls (eg, listboxes, listviews, treeviews, scrollbars -- basically anything that is NOT TF3D) will just completely slow to a crawl. I mean I can actually watch the scrollbar render to the screen over the course of two seconds. It's ridiculous. I use DotFred's task manager to debug things and when I run it and look at CPU usage, it's normal! I mean the CPU is almost entirely idle except for the amount of CPU used by the task manager. Audio also plays smooth, so it seems to be isolated to graphics operations.

I can't find the cause! I also can't find anybody experiencing the same problem (at least how I have described).

The only resolution I've found is to soft reset. But it gets annoying having to repeatedly do that when my phone is having a bad day (basically, the problem occurring several times in one day).

I hope somebody can at least confirm I'm not the only one experiencing this.

I've tried posting at XDA-Developers about this before (where I am much more active) but I didn't get any help (nobody apparently was experiencing this problem.

The only thing I haven't disabled before is my Exchange DirectPush because that is an absolute business need. If that's the cause, I'm going to go crazy because it's the one main thing I can't live without. lol.

Here are my specs:
Carrier: Sprint
Device: Sprint-branded HTC Touch Pro
ROM: MightyROM 6 (also tried MightyROM 5, and stock Sprint ROM)
Radio: Sprint 1.11.00F (also tried Sprint 1.03.15F)
Shell: Mobile Shell 3 (also tried TF3D, Titanium, and standard Today)
