It seems to be happening a lot now. When I watch a YouTube video it leaves ghost image of the YouTube screen. Is there a way to clear my display without logging out?
Does my question make sense?
Thank you

What you experience is also known as "image persistence" or "CRT/screen burn-in". On a CRT I'm not aware of any fix. For an LCD display one recommendation is use a screen saver to alternate between an all white and all black image. If necessary use GIMP to create your images. You could also open up a console with a white background and see if that will ease your problem..

It is not burn-in. It is the image of what was on YouTube. Even if I close the YouTube display right when the video finishes the "image persistance" what I thought was ghost image is there. What clears it is logging out and logging back in again. I was looking for something I could run that would clear the "image persistance" what I thought was a ghost image.

Invoke your desktop's Run Command interface (usually ALT+F2 does the trick) or a terminal and use it to run `xkill`. This will turn your mouse arrow into an X, and you can then click on anything on your screen to kill the process underlying it. Please note that in the case of Flash this may take your entire browser process along with it.
Speaking of your browser, which one do you use? This used to happen a lot back in the bad old days, but I haven't heard/seen this happen in _years_.

What is weird is the "ghost image" shows up on each workspace not just the one where I played the YouTube video. I can also see the traces of the "ghost image" on other YouTube videos I play if I have not logged out and logged back in again. So I don't know how the "xkill" would work on other workspaces.

I actually use three browers: Seamonkey Firefox Chrome

Do you use the flash plugin for youtube or something else? (Native HTML5/WebM support or gnash for instance.) It's quite common for flash video to get displayed as an overlay, which is why this problem persists across desktops. The graphics driver is often involved, what graphics card do you have and what version of fedora?
To kill the flash plugin you can try pkill plugin-container - though that will kill anything running called 'plugin-container'. Odds are flash is the only thing, but you may want to check first.
Other things to try: 1. Make sure flash, Firefox, Fedora are up to date. Check http://www.adobe.com/software/flash/about/ (11.2.202.327 here). 2. If you're using nvidia, give the nouveau driver a go, I'm not having this problem at the minute (though have seen similar ones in the past). 3. Right click on the video, choose settings and change the display settings (left tab), either enable or disable hardware acceleration and see if that helps. 4. Try gnash, or the opt in HTML5 trial (though the latter means you wont be able to access lots of videos).

Only if you remove the flash player (whichever one you use). When you opt into the HTML5 trial, it shows you some clips using HTML5 technology, and others using the old Flash video format.

FWIW, I've been using the ViewTube http://userscripts.org/scripts/show/87011 (a Greasemonkey javascript) for a while now, it seems to work pretty well; basically it uses HTML5. And it's updated regularly (to keep up with the youtube changes).
