[Blocking Requested - why for this release]: SC & Shian-Yow, could you find someone help this bug? It seems a regression. Cynthia, would it be able to reproduce on real TV?

Hi Evelyn, This issue cannot be reproduced on real TV.
James, could you take a look at this issue? Thanks.
OK, I will try to reproduce this locally first.
I try to reproduce this issue on my local build mulet. I found that when in full screen mode, I cannot click anything I saw on the UI... It seems there is a transparent layers covering all the UI elements... Hi Xidorn, I have no idea how could analyze this issue currently. Could you please take a look at the attachment video link and see comment 1 to tell if there is any suspicious commits among this two revision? Please give me some directions for this issue~ I will try to narrow down to the revision that the issue happened in parallel. Thanks for your help :)
I tried downloading both the win32 build and the osx build from comment 1, and ran them with a fresh profile. But it seems none of them can actually play videoes on Youtube for me. And the fullscreen on both of them works fine for me: the static pictures were showed completely, and all controls there worked as expected. The app starts with url chrome://b2g/content/shell.html, but that is a pure black page for me, so I just create new tab and test there. Any suggestion how can I at least reproduce your result?
denominate from 2.5 per comment 7.

Hello Xidorn, I am not quite sure why you got a pure black page since I am not familiar with Mulet. I just followed  to setup my environment. Perhaps you could try |make clean| and rebuild gaia by using |GAIA_DEVICE_TYPE=tv make| to build up a TV profile. Hope this helps. Thanks for your help :)  https://wiki.mozilla.org/Mulet
Oh, I didn't know I would need a gaia profile to get that work. But building a TV profile still has a lot of issues... So I tried to run just a normal |make|. It seems to me that b2g shows a prompt on top of things to ask user whether fullscreen is allowed. That's probably where the issue is? I have no idea. I still cannot completely reproduce this issue...

Is it gecko control or gaia code? Maybe I can try to disable the prompt showing up to see if this issue can be avoided. Thank you~

Is it gecko > control or gaia code? That must be in gaia code. I don't know where the exact entry point is, but I would guess it is a listener of "fullscreen" or "mozfullscreenchange".
Created attachment 8714188 [details] Symptom.png Update the screen shot for the symptom. I can double click on the invisible layer and the cursor will show up... After confirm with Yifan, he can hide this layer by editing the css in system app. He will try to find out why system app displays such layer and provide me some clue. Hi Yifan, Please take a look at this symptom. Thank you.
