This may be related to Bug 607578 which was fixed by bug 596451 accidentally. Reproducible: Always Steps to Reproduce: 1. Start Minefield with new profile 2.

Believe I'm seeing the same issue. Was on this page: http://www.dslreports.com/forum/r25071604-Password-Management.-What-s-recommended~start=20#25079926 Went to reply, & saw http://i56.tinypic.com/2f07z35.jpg (in SeaMonkey ) & http://i56.tinypic.com/xqg9oy.jpg (in FF). I came up with a regression range between 20101110 & 20101111: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=3cd4bdbfce3b&tochange=7e3e4c91c0f7 As you mention, setting dom.ipc.plugins.enabled to false does look to bypass the issue, as does running in -safe-mode. > Callek therube: fwiw: http://hg.mozilla.org/mozilla-central/rev/bdbef533364f (and the rest of its push) looks quite likely My discussion of this should be able to be found (tomorrow) at: http://www.hirsch.sth.ac.at/~robert/thebot-logs/seamonkey-index.xml . Should be the 2010-11-16 log (I suppose).

Happens to be overlayed as shown, but it's look can change depending on positioning. And it is actually an aberration, if you want to look at it that way. Even Alice's black rectangle can be made to "disappear".

(There are other Flash anomalies though not sure if they are this bug too, or can be fixed by whatever ends up fixing this bug, and are more typified by bugs like: Bug 612057 Bug 612154 Bug 612145 )
This bug is also reproducible at http://www.telusmobility.com/en/BC/plans/ and I have also encountered it on engadget.com. Do the following using Windows 7 and then Windows XP: 1. Start with a new profile 2. Disable hardware acceleration and restart (I'm not sure if this matters) 3. Visit: http://www.telusmobility.com/en/BC/plans/ 4. If prompted to "Please select your province," choose "British Columbia" 5. In the absence of this bug, you should now see large headings that include: "Plans", "Clear Choice Voice & Data Plans", "Clear Choice Voice Plans", etc. a) On Windows 7, note that flash background is black (it should be transparent) b) On Windows XP, note that flash is completely white (it should have text) 6. Disable IPC plugins and try again. Notice the page now looks like it should. Compare with Goggle Chrome, Opera, and Internet Explorer, which all render the flash content correctly.

I believe that this is a dup of bug 611698.
Yeah; gotta be. Was hunting for that bug yesterday, but couldn't find it. Thanks.
