After doing a number of port upgrades to try to get firefox 16 to play youtube audio again (still doesn't), I now see that when I put an xterm window over a particular portion of the display, the black areas on the xterm are transparent, and are showing a portion of a youtube page which is no longer playing but which is still open on either a visible or a non-visible (i.e. not the current) tab. The image is from the end of the following page: https://www.youtube.com/watch?v=aHuYmhY-5-g and the video content is https://s.ytimg.com/yts/swfbin/watch_as3-vfl1ubMZd.swf Anyone else seeing this problem? Hmm... this is weird. If I iconify everything except a couple of xterms, xwininfo clicked on the region where the image *was*, which now has only the wm (xfce4) background, the xwininfo gives the window id for the background. This is particularly noticeable in the xfce terminal emulator, 0.4.8, as it comes up with an entirely black background. Gimp, firefox and thunderbird windows don't have the problem, nor does the wm header. I'm guessing this is a result of using the XVideo extension, and not using opengl in the wm, or something like that, based on this article: https://en.wikipedia.org/wiki/X_video_extension Can anyone shed some light on this and how to prevent it? p.s. I can't seem to find how to tell what options a port is installed with, and what the defaults are. I know it's there somewhere... Thanks, Gary
