The XHTML document on http://warsimulator.appspot.com/static/warsim.xhtml is running quite good on Firefox 3.0.11, Safari 4 and Opera 10b. However, the performance on 3.5 is reduced dramatically. Reproducible: Always Steps to Reproduce: 1. Go to http://warsimulator.appspot.com/static/warsim.xhtml 2. Hover over the cells. The cell you are hovering over will be highlighted. 3. Click on a cell to select it and play around with the orange buttons on the top right. They will change the height and the terrain (The buttons on the top left don't have any function yet). Actual Results: When hovering over the cells, the window sometimes stalls for a few second. When clicking the top left buttons, it takes significant time to update the view. Expected Results: It should work at least as fast as in 3.0.11. The latest releases of Opera and Safari are the reference how fast this can work.

Regression range seems to be http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=1949346e6006&tochange=6e39da3e3e20 I tested the top orange cell: increaseHeight. Clicked 20x per 10 seconds and a "bad" build was not yet finished after 10 seconds.

Almost certainly bug 455984. I guess the first thing to do is to reduce the testcase.
The testcase uses opacity all over. Restoring the opacity optimisation fixes this.
