1708518 - The restore button in Firefox with CSD mode doesn't match the one displayed in native Qt applications

Status: RESOLVED DUPLICATE of bug 1574291

(Core :: Widget: Gtk, defect, P2)

Description

[mi2rivtj]

Attachment: bug happening in Firefox.mp4

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:88.0) Gecko/20100101 Firefox/88.0

Steps to reproduce:

Use Ubuntu with KDE:

1. Open Firefox
2. Maximize the window

Actual results:

The restore button is the same of the maximize button. KDE uses Breeze-GTK, but this problem also happens with other themes such as Qogir. The weird thing is that this doesn't happen in Adwaita GTK.

Doesn't seem so be a theme issue because the restore button shows normally for other GTK applications such as GNOME Disk Utility and GNOME Cloks (when using Breeze, Qogir and others).

This also happens in FF 89 beta 5

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.
