When I select text in Chrome and then click somewhere else on my desktop so that the Chrome window loses the focus, the formerly blue text selection becomes almost white which makes it impossible to read the selected (and also white) text.
Other applications are not affected (although their inactive selection color is also brighter than the active selection color).

For some reason, bugs.kde.org is one of the few websites that don't have this problem with text selection. However, the problem does appear with selection input fields (such as the Component and the Version fields in the guided editor or the advanced search). When they lose focus, the selection becomes unreadable.

Reproducible: Always
