I have a very similar problem using Mozilla Firefox 1.0.4 (Mozilla/5.0 (Windows;
U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4). Although I
can't check the page the original poster referenced, so I can't judge how
similar it is.
When using tables and giving different cells different opacities (based on
:hover in my case, but I'm not sure that's a requisite) drawing becomes very
slow (and somehow different when using borders) when some cells have an opacity
< 1 and some (one?) cell(s) have opacity 1. When all cells have opacity < 1 or
opacity 1 nothing seems to be wrong.
I have attached a test document (opacitytest.html) to illustrate the problem.
Opacitytest2.html is the same document but with all non-hover cells using the
"default" style (so probably opacity 1), please note the difference (compared to
opacitytest.html) in speed as well as the difference in handling the size of
cells with borders.
