Added a post to redirect people with this issue to this new thread:

Additionally, I have been running the Stock Rooted ROM from 6/13 (with camera fixed) along with the modified Radio from the Darkside Evolution.3 thread for the last 3 hours.

I have tried to reproduce the issue which I have been able to reproduce in under 30 minutes on v4 and v5. But so far I have not been able to reproduce it. This is with only an extreme bare minimum of apps installed on top of the stock ROM (that I can't live without).

I am going to start restoring apps and widgets to the phone and then running the reproduction steps until I hit a hang. Then I will work on isolating the exact app or widget that is causing this problem.

Installed in initial version (my must have apps, no widgets).

Unable to reproduce an app launch hang.

SWTOR security key

Google Authenticator

TB

WeatherBug

Amazon Appstore

Google Drive

Gentle Alarm

SwiftKey X

Tapatalk

VIP Access

Google Voice

Installed in second version (my most suspect apps, but still no widgets).

Unable to reproduce an app launch hang.

Facebook

WhatsApp

Unlock With WiFi

Skype

Scorecenter

SetCPU

QuickBoot

ROM Manager

Multi Mount SD-Card Lite

Well I haven't gotten a hang yet on the Stock ROM but I did get it to soft boot TW and disconnect my WiFi and BT while streaming music on Google Music and setting up Sync on Facebook. So Facebook is looking quite suspicious. Has anyone reproduced the app hangs without Facebook installed?

This soft reboot of TW also caused the time to be switched to GMT which has been reported on the TMO support forums with the stock ROM.

I ran test #2 here for well over an hour and I could not get another soft reboot or a single app launch hang. I did get some stuttering of music and slowdowns due to overloading the CPU and/or RAM and garbage collection. But nothing was unrecoverable or did not resolve itself with some time to let the CPU catch up. No reboots were needed.

Installed in third version (my most suspect apps AND widgets).

Unable to reproduce an app launch hang.

All apps from tests 1 and 2.

Scorecenter widget

Scorecenter video widget

Agenda widget

News and weather widget

Multi Mount SD-card lite widget

Google Voice widget

Digital Clock widget

I ran test #3 here for about another 45 minutes and saw no difference in performance or behavior. I did note that while the Multi Mount SD-card lite widget does show up in TW. Clicking on it does not appear to work (it delays a while and then gets su access, but never displays its dialog confirmaton). But it never caused a soft reboot or any app launch hangs.

Installed in fourth version (all of my apps, widgets, GO Launcher and Apex).

Unable to reproduce an app launch hang.

I've been banging on the stock ROM with all of my apps and widgets installed for over an hour now. I've seen 2 soft reboots, usually when RAM/CPU usage gets high and the OS can't handle things. It is possible that this bug triggers a soft reboot in the stock ROM but instead triggers the app launch hang bug in darkside ROMs. But I haven't generally noticed the phone slowing down and music stuttering when I've had the app launch hang issue, but I do very much notice it on the stock ROM right before a soft reboot.

I'm going to run this stock ROM w/ all apps/widgets over night and see if I can make it through. So far I've only been using TW. But in another hour or so I'll enable Go Launcher and Apex for a couple hours each.

Overnight update:

I ran Apex for about 30 minutes, no issues. Ran Go Launcher for about 2 hours of use plus overnight time. Everything is still working just fine this morning. Already put in about an hour worth of use this morning with no issues yet.

So far after over a full day or testing and following reproduction steps for hours (that I can cause an app launch hang with on Darkside v5 in ~20 minutes), I am not able to cause an app launch hang on the stock ROM.

Here are the stock issues that I did find, which if seen on Darkside should not be reported against the ROM or to TDJ:

1) soft reboots when OS gets overloaded, disconnects wifi, BT, etc shuts down all apps.

2) Soft reboots cause timezone to get set to GMT

Edit 06/27: I've now been running the Stock rooted ROM from Mr.X for at least 3 full days of regular usage without a single app launch hang. During regular usage, I haven't seen any of the soft reboots or timezone issues either. I have run into issues with uninstalling bloatware though. I keep getting Delete Failed when trying to remove it from /system/app.
