Summary:                    _NET_WM_STATE_FULLSCREEN issues with xfwm4
Description: 
When I try to enter full screen mode with xawtv or xawdecode (TV viewing
apps), instead of enjoying the TV picture in fullscreen (this is what I
get with kwin, fluxbox, fvwm etc.), with xfwm4 and metacity, what I see is
basically:
- the xfce4 taskbar at the top
- xawtv's window decoration
- xawtv's left window frame
- I get the TV on the rest of the screen, although it's truncated.

Expected result: Have the TV in fullscreen like I get with other window
managers

I think it's the same issue that was brought up here for metacity but
never resolved:

What version of XawTV? 

I'm really having no problem at all with XawTV/fullscreen here.

My bad.

I had not tested xawtv in a while. And since at some point I had the same
problem with both xawtv and xawdecode, and since I still have it with
xawdecode, I assumed that the problem would still be there with xawtv.

Xawdecode's website is http://xawdecode.sourceforge.net/ , and source &
binaries can be downloaded from
http://sourceforge.net/project/showfiles.php?group_id=67268

However, I also have a fullscreen bug with xawtv & xfwm4, but a different
one.
I run X with a custom resolution:  1112x834 (it gives me more space than
1024x768 and a better refresh rate than 1152x864).

If I set my resolution to 1024x768, fullscreen works fine, but at
1112x834, the fullscreened xawtv window does not cover the whole screen.
The bottom and right part of the screen show the desktop. On the
screenshot, the TV surface (blue) measures 1088x816.

(again no such problem in other wms like fluxbox or kwin)
Here's the modeline I used if you want to try to reproduce it:

ModeLine "1112x834" 99.37 1112 1160 1400 1496 834 836 848 874

That's prolly because the aspect ratio is not the same. xfwm4 (unlike many
other WM, including metacity for example) does implement aspect ratio and
check for it even in fullscreen mode.

Can you try this version:

http://www.xfce.org/archive/test/xfwm4-4.0.6-cvs.tar.gz

This one ignore the app's size hints in fullscreen mode
