[Blocking Requested - why for this release]: Rotation feature displays obvious visual imperfection. adding qawanted for branch check and regression range check.

Jonathan, can you take a look at this please? This looks to have been caused by the landing for bug 1155261.

It seems really surprising that bug 1155261 would cause this, as it should not have had any effect except on text with writing-mode:vertical. I'll try to reproduce this locally and look into it a bit more, though it may take some time (last time I tried to build for flame -- quite a while back -- I couldn't ever get the build to complete; I forget the details, though). Can you try a build with bug 1155261 backed out, to see whether that actually makes the problem go away?

With a Flame running build id 20150501010203, I can reproduce this some of the time. Playing a video and repeatedly rotating the phone back and forth shows the glitch fairly often but not always; sometimes the transition is "clean". It looks to me like this may be a timing issue where a couple of properties -- the scale of the video, and its position -- are being transitioned independently, and if one of them gets significantly delayed for some reason, we get the ugly intermediate state with the mis-positioned video. But I don't see any plausible connection to bug 1155261.... Unfortunately, I haven't yet managed to get my local build to complete, so have not been able to experiment further. Maybe someone with a working build could try backing out bug 1155261 to confirm whether that fixes the issue?

You are correct. We backed out the commit and the issue is still occurring. Sorry for posting the wrong window. Apparently, the reproducibility rate drops. We are getting another window now.

This issue seems to actually be two issues depending on which app you open it on. In Gallery, I was able to reproduce this issue on 3.0, 2.2, 2.1, and 2.0 Flame builds which would indicate that it is not a regression. In Video however, I was only able to reproduce this issue on 3.0 Flame builds. I will finish getting the window for the Video app tomorrow.

Looks like I was one build off... Blake, can you take a look at this please? Looks like the landing for bug 1146729 might be the cause here.

I has confirmed this bug is caused due to the landed patch in bug 1146729. I will check it.

Blake, could you comment this? As my test, issue is gone on foxfooding phone (Master).

(In reply to Bobby Chien [:bchien] from comment #11) > Blake, could you comment this? As my test, issue is gone on foxfooding phone > (Master). I cannot see this problem on my foxfooding phone either. There should be no codes specifically changed for this bug. njpark, Would you mind checking again if this problem can be seen on current master code base? Thanks!

The issue is gone on my flame device as well. I should close this bug. Thanks!
