Attachment: Firefox Tab and Tool Bars Bug with swf file

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160315153207

Steps to reproduce:

I open a .swf directly in a Firefox tab (not embed in .html page). 
Then when resize the Firefox window or when I open/close other tabs there is a display bug in Firefox tab Bar and tool Bar.

My conf is Windows 8.1 64 Intel HD Graphics 4400 with up to date drivers, Flash (debugger for Firefox) up to date. I tried Firefox in safe mode and with/without Graphic acceleration on Firefox and on Flash and I have the bug in all cases.

My laptop with different Hardware and Win 10 but same softwares (Firefox and Flash debugger) doesn't have the Bug.


Actual results:

There is a display bug in Firefox tab Bar and tool Bar. The text in the bars are unreadable. It is printed multiple times over itself as in the image.


Expected results:

The tab bar and the tool bar should be normal.

Sure, it is in French but shouldn't be too hard to understand. If you need translation or more info feel free to ask.

With the search "site:mozilla.com filetype:swf", there seems no valid swf file now.

I tried to reproduce the problem on my laptop(windows 8.1) with direct swf file load. But I could not reproduce the problem with/without hw acceleration.

I saw similar rendering problem on my laptop(windows 8.1), when I enabled hw acceleration and warp. But when the warp was enable, I also saw content rendering problems. warp is disable on nightly by Bug 1260507.

Poker, do you still see the problem? Can you check if the problem happens on nightly?

Hello,

I still see the problem on Firefox. However, I installed Nightly and I don't have the problem on Nightly, thank you.

I guess this problem doesn't impact many users. I will try to reinstall Firefox in a few days and let you know if that solved my problem.

Regards
