This likely regressed very recently. I first noticed it with today's nightly.
I assume YouTube is running Flash :-) Possibly a dup of bug 903296. Please post a link to the YouTube video you tested with.

Are you also seeing this with other Flash and Java content?
Yeah I see it on all Flash and Java.
So, bug 903296 is also on Retina and Flash & Java, but isn't a recently introduced regression. Maybe we are seeing some intermittent issues?
David, does this bug happen with a clean profile? If it doesn't, look at about:support in your old profile for clues. If it does, can you remember any OS-level changes you made recently, or any new software you installed? What version of Flash do you have?
(In reply to Steven Michaud from comment #7) > David, does this bug happen with a clean profile? Yes - just checked. > If it does, can you remember any OS-level changes you made recently, or any > new software you installed? Hmm... Nothing springs to mind. Note as for nightly regression window I'm not sure how recently I updated but I definitely updated this morning and the bug started happening. I don't recall any other updates recently. Likely a red herring but yesterday I was running a few browsers I don't normally run (chrome, safari), just to test some interoperability during a w3c call. I've been putting off an OSX update for printer and airport stuff. > > What version of Flash do you have? Version: 11.8.800.94
Summary: Youtube video appears to be 1/4 the size. → Youtube/Flash/Java appears to only show the top left 1/4 of the content, cutting off the rest.
I *can* reproduce this bug in today's mozilla-central nightly, but only on a Retina MBP, and then only with HiDPI support on. I couldn't reproduce bug 903296 a while ago. I still think this bug and bug 903296 are most likely the same bug. But something seems to have changed very recently on the trunk to make the situation worse. I'll look for the regression range.
Here's the URL I used to reproduce this bug: http://mirrors.creativecommons.org/getcreative/
For me these start with today's mozill-central nightly. Which implies this regression range: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=bb025b6949e8&tochange=d136c8999d96
I can't begin to guess which patch in that range caused/triggered my ability to reproduce this bug. I guess I'll have to hg bisect.
You can use the tinderobx ftp mozilla-inbound builds to avoid building locally. It's annoying because you can't sort by landing order and have to check the .txt but it's faster.
I prefer to use hg bisect. Yes it can take a long time. But since it doesn't require much thought, I can do it "in the background", in between other tasks. I can even leave it overnight and come back again the next day (as I did this time). What hg bisect found puzzles me. It tells me that the following patch triggered this bug. (By the way I've confirmed this result "by hand".) http://hg.mozilla.org/mozilla-central/rev/252dbb41d609 Bug 900133 - Enable new textures on OSX. r=nical author Nicolas Silva <nical@mozilla.com> Tue Jul 30 19:37:13 2013 +0200 (at Tue Jul 30 19:37:13 2013 +0200)

Since I'm the one who wrote the code that allows plugins to work in HiDPI mode, I'm probably best placed to figure this bug out. But even for me it'll take a lot of debug logging and head scratching. Do you have any ideas, Benoit?

Seconding that this problem has returned just with the Nightly I updated today. (My last update would have been one or two days ago.)

(In reply to Steven Michaud from comment #15) > Do you have any ideas, Benoit? This was just discussed in a meeting I was in. Looks like this is a dupe of bug 907792. We're hoping to fix it ASAP to avoid turning off OMTC mac.
