Description

13 years ago
If you go to the URL above and click on one of buttons (in the menu bar just
below 'Ministry of Education and Human Resource Development. What a name !), the
pull-down menu is obscured by the flash animation. 

On Mac OS X and Windows, the pull-down menu is rendered *on top of* the flash
animation. However, on Linux, the pull-down menu goes *beneath* the flash
animation. 

I don't think this is flash-specific because without the flash plug-in
installed, I found that the default null plug-in also hides the pull-down menu. 

Because I'm not sure who knows about this stuff, I'm just adding  a few people
randomly. Sorry for that, but hope that will help get the attention of the right
person eventually. 

On Mac OS X, I tried 1.7release and the current trunk. On Windows, I tested
firefox 0.9.x. On Linux I tried firefox 0.9.x, current trunk and Mozilla suite
1.7 and the trunk build.

screenshot demonstrating the problem

this was taken with Mozilla 1.7 on Linux. The same page doesn't have any
problem on Windows and Mac OS X.

I'll try to come up with a reduced test case later.
don't you need to set wmode="true" on the <embed>?
We definitely have other bugs about this issue on file

Thanks for the pointer. All those bugs seem to identical to this one except that
this one manifest itself only on Linux. Failing to find similar bugs with 'word
matches', I tried 'pp' in keyword with the platform and OS set to PC/Linux.
Nothing relevant turned up, which is understandable given that all those bugs
are XP (or were reported on Windows). 

As for 'wmode', it's set to 'transparent' in the page as below

<td onmouseover="swapTopmenu();"><embed src='/flash/main.swf' width=768
height=141 wmode=transparent></td>


When I first observed this bug, I thought the web site has an evangelism issue
because Korean (government) web designers/admins are very bad at making their
web sites compliant to the standard (if they don't block non-IE browsers
downright). Then, Windows users told me that it's fine with Firefox, which I
confirmed myself. I went on to test it on Mac OS X and it's also fine there. 

I definitely need to make a reduced test case to see what's going on. 
Please make sure that your version of flash on Linux is new enough to support
wmode (such support was added by flash much later than on Windows/Mac).

The first example at  
http://www.macromedia.com/support/flash/ts/documents/wmode.htm

works as described, which, I believe, indicates that my version of flash
supports wmode. 

Can anyone else reproduce this problem on Linux?

JS source is here:
http://www.moe.go.kr/common/js/JSFX_FadingRollovers.js
there doesn't seem to be any Linux/Unix-specific code path, but maybe the
opacity code behave differently on Linux, referring to such lines:

document.write('<STYLE TYPE="text/css">.imgFader{ position:relative;
filter:alpha(opacity=0); -moz-opacity:0.0 }</STYLE>');
[...]
img.style.MozOpacity = img.index/101;

I used FF trunk 20040902 + Flash 7.0r25 on Linux.
OK, I see this on Linux too.  A testcase would be very nice indeed.

Shows the z-order bug of plug-ins in Mozilla
Not related to this bug; you're just running into the null-plugin not being windowless.

flash plugin 9.0.115 has been released and I have tested http://www.adobe.com/ with trunk build on Mac and Linux.

Mac seems to support windowless mode but Linux not.
