Weird gtk breeze dark issue

I got this strange bug with flatpak firefox im on fedora 42 up to date i think its a possibly a bug but as far as i know its affected only flatpak firefox

instead when i set it up to non maximise windows it turns just ok with the dark scheme…

Hi - this looks like the following bug showing up in Breeze Dark: 416353 – Maximize button is miscolored when maximized

It looks like there was some work happening around that bug report a couple of years ago. At this point, it may just need someone with the time, ability and interest to figure out how to complete a fix there.

thanks for your help, i solved this little issue by using the rpm firefox btw
maybe in the future flatpak firefox will be the default one
