Full opacity of track row colors after OS upgrade.

Bug Description

I ran into exactly the same problem again after almost 2 years of flawless function. Most of my tracks are color coded. Normally the color in the track list is alternating low brightness. Now all the lines are full brightness, except for the columns “preview”, coverart" and “no. played.” (I hope I have translated that correctly), see attached screen shot. All I did was to upgrade ubuntustudio from 24.04 to 26.04, then reinstall the latest stable mixxx ppa. Before the upgrade my mixxx version was 2.5.x (the latest), now it’s 2.5.6.

Version

2.5.6

OS

Ubuntustudio 26.04

Edit / Note (@ronso0) We figured this is a bug in the KDE themes Breeze and Adwaita. A workaround for current versions (until #17043 has been merged) is to explicitly use a different style. Fusion and Oxygen have been reported to not show the opacity issue:

mixxx -style Fusion
