1452520 - [KDE] Selectors that have .solid-csd class do not work

Status: RESOLVED INVALID

(Core :: Widget: Gtk, defect)

Description

[Vlad Zahorodnii [:zzag]]

Attachment: Screenshot_20180409_020013.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:61.0) Gecko/20100101 Firefox/61.0
Build ID: 20180408100251

Steps to reproduce:

* Install latest KDE Plasma (at this moment, 5.12.4)
* Use Breeze GTK theme(Go to System Settings > Application Style > GNOME Application Style (GTK) and pick Breeze under "Select a GTK3 theme")
* Disable title bar in Firefox
* Unmaximize Firefox (if it was maximized)


Actual results:

Corners are round. See the attached picture.


Expected results:

Corners should have been sharp because Breeze GTK has the following rule:

```
  .solid-csd decoration {
    border-radius: 0;
    margin: 0;
    padding: 0px;
    border: none;
    background-color: #556068;
    box-shadow: none; }
```

Also, I've tried using the following rule but without success

```
.solid-csd headerbar.default-decoration,
.solid-csd .titlebar.default-decoration {
  border-radius: 0; }
```

Without `.solid-csd` class it works, corners of Firefox are sharp.

Most likely, Firefox somehow mishandles rules which have .solid-csd class in their selectors.

That's because "solid-csd" is a class used for decorations for uncomposited environment, without alpha blending and semi-transparent shadows. We use "csd" class as we support transparent window borders.

So, indeed, it seems like that's theme related issue (related to css precedence, I guess).

I'll investigate this as we need to support KDE somehow.

KDE is supported well now so closing this as a theme bug.

No, I still can't resize the window.

Can you please file a new bug and attach some screenshot there? This one is about Breeze GTK theme on KDE.

That's because of Breeze GTK theme. See

If Firefox relies on a buggy dependency to realize a feature, the bug should either be reported and fixed upstream or circumvented in Firefox. Should we reopen this bug until it's fixed or mark it as wontfix instead? It's all, but not invalid.^^

Also, I can confirm that now corners are sharp. :)

I reopened bug 1453386 as it's about the resize.
