Status: RESOLVED DUPLICATE of bug 540719

(Firefox :: General, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 ImageShackToolbar/5.2.3 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 ImageShackToolbar/5.2.3 (.NET CLR 3.5.30729)

With certain flash video websites, when I attempt to full screen the videos, the video is transferred to the primary monitor, regardless of which monitor the embedded video is actually on. The easiest to reproduce is Hulu, as all of it's videos display the same behavior. Websites like YouTube, however, I have no such issue, and the full screen behavior selects the monitor to full screen based on which monitor the selected window is on. This did not start until recently. The only work around I have found for it as it relates to Hulu specifically is to use the "Pop out" option, as when I do this and full screen that video it works as intended. 

This does not seem to be related to flash as I have opened the same videos with IE and have no issue.

Also, something that may be important to note is that I am running the dual monitor via a HDMI cable from my p-7805u (vista x64). 

Reproducible: Always

Steps to Reproduce:
1.Visit various flash sites
2.Full screen a video on second monitor
Actual Results:  
The video is transferred to the primary monitor, leaving the secondary monitor with the exact same web page without the video window.

A screenie:

Note that the screen on the left (the primary, marked 1) is a 1440x900 screen, and that even though the screenie implies that it isn't full screen, it's actually just the discrepancy to the secondary monitor which is 1920x1080 (marked 2). 

Expected Results:  
The full screened video plays on the secondary monitor, just like it does with IE and most other popular sites.

Does it happen in a new profile? I see you have the image shack toolbar. also, what version of flash is this?

WIN 10,1,51,66

I use the beta 10.1 because running anything off a 2.26 dual core via 32 bit processing isn't very impressive, and the video tends to stutter. I need the GPU acceleration from this beta version to alleviate that.

Also, what do you mean new profile? Do you mean when I am not logged into Hulu?

Good call -.-;
Indeed, it works as intended when I switched to a new profile. What could be causing this? A add-on? A Firefox preference?

Anything? I have gone though my options and add-ons and i don't see anything that is causing it off hand. And why with some flash videos and not others?

I just formatted to install Windows 7. I had a fresh install of Flash, Firefox, ect. and I'm back to the same issue. I even tried to create another profile to no avail. What is pushing this over to the other window?

It seems to be the GPU acceleration. Whenever a flash video is GPU accelerated it appears on my primary monitor. Whenever a flash video can't be accelerated by GPU it appears correctly on my secondary monitor.

Also a possible reason why IE works correctly for you Anthong, is that maybe you didn't install the beta activex plugin for IE. They are two separate plugins. Perhaps you're only using the beta on Firefox.

You, sir, have nailed that one. That actually makes a lot of sense. Flash is really holding me back from a full x64 PC. I can't use a x64 browser until Adobe gets around to creating it.

I have read that it's the next big release after 10.1, and they already have one available for Linux.

Actually I can not confirm this problem with the latest flash beta. I just tried to reproduce using 10.1.51.95. Try the newest beta and report back.

Will do.
