User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0 Build ID: 20150122214805 Steps to reproduce: When accessing to some webs with flash components (like http://gtestimate.com/gti/InterfaceEntryPoint.aspx?requestId=1775084180210772158138451955514544251191), some of these components are hidden or not showed. This hidden swf is interactive, and in spite of been hidden, you can click on and get results. In my example, the issue is random. You have to get in and some times, the swf in the bottom right, is hidden (it's an interactive vehicle image which let you select different areas). This isse only happen in Firerfox, from v34 edition (also in v35). In other browsers it works ok. I have already test with all complements disabled (except Flash). Actual results: The swf component in the website is not showed. It is hidden randomly, you can click on and get results (interactive) Expected results: All swf component shoudl be showed properly.

I opened the link in comment 1 ten times in a row in the same tab on Nightly 38 (2015-02-11) on OSX. In all cases the page appears to load the same way. Am I missing something?

I was able to reproduce on Firefox 36 Beta 8 on Windows 7 SP1. Setting tracking flags for 36+. No need to track ESR38 yet as we can still fix this in 38. Milan - We have STR. Can you please have someone investigate?
All test we did were in Windows environment (in my case, Windows 7). Thank you!
Bas, let me know if you can't reproduce this.

I will look into this.

35 shipped with that bug, looks like it is going to be the same for 36.
I've managed to reproduce this once, but it only seems to reproduce very rarely for me. I'll look at some things to change to affect the timing to see if I can increase reproducibility.
I've only been able to reproduce this twice in many attempts. Sadly it makes it very hard to do any sort of serious diagnosis of the cause. Do we have access to any machines which have better reproduction rates for this bug?
Flags: needinfo?(milan)
Yes, we do have a way of reproducing this (see comment 4), at least we used to; the link from comment 1 now gives me a server side error. Also, this bug is almost an opposite of bug 1132382, where opening in a new tab doesn't run Flash, but reloading it does, and the problem is not Windows specific.

Hrm, I tried on another machine and it also doesn't seem to have the problem. I did see a bug like this on release on a completely different website, but that didn't seem like a graphics bug to me at all.

Let me see if I can reproduce it on my Windows 7.
Presumably the request id from the link in comment 1 has expired. Alex, can you still reproduce this issue? If so, can you post a new link? If I can repro this on Linux I can try to get an rr recording and debug.

I have just tried on Firefox 36.0.1 and it is still happening. You can access in http://gtestimate.com/gti/InterfaceEntryPoint.aspx?requestId=2341562310255113127411931915272103749 and at the bottom right, you should see a dynamic composition of a vehicle. But the most of times this box is empty. If you move your mouse over it, you will notify that there is something here (the dynamic image is here but it does not appear). And sometimes, when clicking on this box, the dynamic image appears suddenly. I tried on my Windows 7 x64. Do not hesitate to ask me any doubt. Thanks a lot!

I can reproduce this in 37 beta by loading the URL from comment 15, then doing a reload. I see the car in the bottom right after the load, but not after the reload. Switching tabs, it comes back. Doing a reload after that - doesn't show up. Is this using Stage3D?
Flags: needinfo?(milan)
I'm not able to repro on Ubuntu with FF 36 on that URL. I'll leave it to the windows crew then (better debug it before the request id expires again!)
When mucking with SWF permissions, I see "cd.GetLaterality is not a function" message.
Summary: hidden pictures → Flash not showing on some car site

I suspect this is the same bug as bug 1123400. That one is probably a better bug to track with a more isolated test case. Since I can't reproduce either though, I'm not 100% certain.
I confirmed that disabling the readback layer fixes the problem.
It looks like the plugin layer is being reordered so that instead of having PaintedLayer ImageLayer ImageLayer we end up with ImageLayer PaintedLayer ImageLayer
Without this we early exit from the loop in ShadowLayerForwarder::InsertAfter which causes us to insert layers after the ReadbackLayers in the wrong order.

Release Note Request (optional, but appreciated) [Why is this notable]: Regression from Firefox 34, common when Flash is used. [Suggested wording]: A regression that could lead to Flash not displaying has been fixed. [Links (documentation, blog post, etc)]:

Liz added this to FF39 release notes. Updating the relnote-firefox to reflect that.
