Created attachment 171497 [details] Screenshot of Firefox with Restore Down dark and not visible SUMMARY The Restore Down button on Firefox (flatpak) can't be seen in dark mode. I am using KDE Plasma 6.1.1 (Wayland) on Fedora 40. This issue first appeared after upgrading from v6.0 to v6.1. Sometimes all of the buttons can't be seen (Minimize, Restore Down, and Close) however this usually goes away after rebooting. I don't know why or when they go dark and cannot replicate it, but it only happens occasionally. However, the Restore Down Button is always dark. If the Firefox window isn't selected or active, you can see all of the buttons normally, but as soon as it's brought into focus, you can't see it. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora Linux 40 (Workstation Edition) x86_64 KDE Plasma Version: KDE Plasma 6.1.1 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.2-1.fc40
Thank you for the bug report! There is another bug report open about miscolored unmaximize buttons for gtk apps; While that bug is technically refrencing light themes, I suspect it is the same issue. That report also seems to contain a workaround that you could try if you are affected by this issue. *** This bug has been marked as a duplicate of bug 416353 ***
