CSS tree selection issue on Linux only [message #1787402]

Hi,

We have a RCP application using CSS for styling. It works fine on win; but on Linux, the tree selection is messed up. The problem can be duplicated with the attached mail example.

When the application is started, it shows as in start.png; with some selection/expansion on the tree, it shows as in withSelection.png.

If I remove "swt-selection-background-color: #AFD7E1" from the default.css tree element, the problem goes away.

Tree {
color: #000000;
background-color: #ffffff;
swt-selection-background-color: #AFD7E1;
swt-hot-background-color: #DAECF0;
swt-selection-border-color: #AFD7E1;
swt-hot-border-color: #DAECF0;
}

I am wondering if this is a know issue? Or some setting on the linux machine (using CentOS) that might cause the issue? Any suggestions on how to solve it?

Appreciate much for the help!

There are known issues with trees and CSS on Linux. We've papered over some of them, but there are still some edge cases. It's a tough nut to crack, unfortunately.
