This was done with Fedora 23 using KDE and Broadway. The results of my tests were the same in GNOME and KDE, so I just filmed it in KDE. I couldn't do any additional tests in Wayland instead of Broadway because neither of my laptops will run it at the moment.
Notable bugs in the video:
*Clicking on SWT-rendered pieces is offset by ~1cm.
*Long-running operations hang the UI (not shown because they hang...).
*Clicking to expand items in the project explorer kills Eclipse.
*Almost all edges are incorrectly drawn on dialogs.
*Some lists require resizing the view screen to refresh the content.
Please let me know what you think. In particular, if there are things that you believe are missing, then I would like to know about them so that I can try to shoot them and get them in the video.
I think this is really useful footage and it will illustrate what we need from the community very well. There is about 14min of footage, which I can cut up into shorter segments illustrating individual bugs and dub audio over to explain what is happening. My script for the video is:
