Opera 7 shows a rough quantization error when a margin or a padding is expressed in em units and the value of the property is greater than (about) 20.47em. In these conditions the decimals are simply ignored. For example, all margins of 21em, 21.1em, … up to 21.9em are rendered exactly the same. This is not a simple rounding error.

This site is no longer maintained. I’m sorry, but it’s just too much work for too little return. You can continue to browse old bug reports, though.

I've also noticed that Opera and Konqueror seem to round percentages to integers. Note to developers: just use floating point!

Yes, both Opera 7 and Safari seem to truncate percentages values to integers (see http://www.brunildo.org/test/percmarg2.pl should display a black diagonal, not a staircase...)
