Created attachment 113403 [details] near invisble window control buttons with 5.13 On update to Breeze gtk theme from 5.13.0, compatibly with Firefox build in dark theme (selectable in customise/themes or default in Firefox Developer) is broken insomuch that the close/restore/minimise window buttons are dark on a dark background and only barely discernable on some displays, and next to invisible on others. Screenshots of the issue attached, along with a before example showing the result when Breeze GTK theme on the same system is downgraded to 5.12.5. The issue also occurs when using theme with dark titlebars from the new Firefox 'colors experiment' from Firefox Test Pilot.

Finally found a bug report for this, but I'm surprised nobody has noticed that it's like this for *all* GTK3 applications that use client-side decorations. Try installing something like gnome-characters and you'll see it have the same bug. It also won't change from a dark color to a light color when the window is no longer in focus, instead staying the dark color.
Still valid for plasma 5.14 beta, Firefox 62 on Arch Linux.
This bug persists. Firefox 65.0.2 Operating System: Arch Linux KDE Plasma Version: 5.15.3 KDE Frameworks Version: 5.56.0 Qt Version: 5.12.2
This doesn't seem to be present anymore in Plasma 5.16, can someone confirm?
Same, seems fixed now.
