[Woodduck][System][TP Frozen]App frozen because of multi-window's state are "active" in system
Description: The screen is frozen at FM radio(can be Messages App or any other app) during following operations(See Reproduce method). Touch & tap any point in FM radio, no response. 1. Press or long touch home key, cannot return to homescreen but vibration still responses. 2. Press volume up & down, it works as expectation. 3. Press Power key, the screen can be lighted on & off. 4. Long press power key, sleep menu is showed as expectation, all the options can be chosen and no frozen on that menu. 5. utility-tray can be dragged down and no frozen 6. Lockscreen works as expectation. Reproduce method: 1. touch & tap（two fingers) on TP more than 1000 times. 2. launch any App more than 100 times with high frequency. 3. light on / off the screen more than 100 times. 4. Dial & answer calls more than 30 times. Probability: 2 out of 8 MS during 3 hours test. Analysis: See the attachment(issue MS is frozen at Messages App). issue.jpg is the snapshot of children window list under id="windows" node in system app in issue MS. ok.jpg is the snapshot of children window list under id="windows" node in system app in MS without the issue. We doubt some logical defect causes the wrong state in id="homescree" node. It is impossible that both FM Radio and homescreen are activated at the same time under this circumstance. And still, you can get the mtklog from: http://pan.baidu.com/s/1gdKzjm7 https://drive.google.com/open?id=0Bz6aW3cbHgB8Y3RQV1VsVW4xbDg ==================================================== Analysis from Zhangjin: Attachment: Message-Contacts-Homescreen.log Opened Logs in app_window.js and app_window_manager.js. Switch between Message/Contacts/Homescreen, and finally end at a state that Contacts and Homescreen are both 'active', Contacts covers above Homescreen and will not disappear when press home key. ====================================================== Message-Contacts-Homescreen.log2 another log, device freeze at Message.

We have the following workaround solution since we don't know the root cause of this issue. See the patch.

Hi Etienne: Sorry for keeping asking, do you think it's something related to Gaia:system so you'll be able to help, or it in fact points to other module so you can help advise me a more suitable person to look into? Thanks in advance!

I'm happy to help on Gaia master (or other gaia public branches) bugs, with STR based on those branches. But I can only work on the "root" issues, can't help when there's bug with a non-reviewed workaround.
