Thunderbird wide scrollbars

[Beerislife]

I've started having problems with the scrollbar width with Thunderbird 78 from the Ubuntu Mozilla Security PPA. As you can see, the folder list and message list both have massively wide scrollbars but the message pane has a normal Breeze style scrollbar.

OS is KDE Neon 20.04 fully updated. Style is Breeze. Plasma Theme and colours Arc Dark.

If I go into settings and make sure the GTK Theme is Breeze, it becomes normal again, for a few seconds, then goes wide again!

I might remove the scrollbar arrows I have set in gtk.css and see if that helps but I doubt it.

I seem to have narrowed it down to ANY dark colour scheme. All light schemes show normal width scrollbars. So, it's a choice of wide scrollbars or blinding myself with lighter colours!

Going back to TBird 68 fixed it. It's not worth fighting with.

I hadn't really noticed and just use it the way it is.

I'd rather have the security updates.

My scrollbars are normal with a light theme. I thought they were abnormal a couple of weeks ago when I went from Mint to Kubuntu. Tbird bars were wide in Mint, but did not bother me.

Little things like that annoy me no end! ��

Not worth filing a bug report over?

I kind of like the extra space for reading the message, but am willing to confirm it exists.

Usually, yes, but I have more pressing things to worry about, like going out of business and having no income because of Covid-19.

I think I just fixed this!

Go to Edit > Preferences > General

Scroll down to the bottom and click on Config Editor.

In the Search box put SCROLLBAR

and you want to set layout.css.scrollbar-width.enabled;true to false.

Done.

Edit: Nope, it worked for a while then went back to fat!

hi
I replied to the thread below but just for grins and giggles I found this:

https://askubuntu.com/questions/9254...crollbar-width

Long discussion at Open SUSE about various apps and how they approach scroll bars and the desultory discussion about "just use the"mouse wheel" along with a lot of discussion of fiddling with GTK.

The strange thing is this happens on my main machine running Neon and on a Linux Mint Cinnamon machine that was previously running Kubuntu (Separate /home) Two other machines that have only had Mint Cinnamon installed have normal scrollbars!

In Thunderbird, I use ~/.config/gtk-3.0/gtk.css to control the scrollbar width. This is the file:

scrollbar, scrollbar slider,
scrollbar.vertical .slider {
  -GtkScrollbar-has-backward-stepper: true;
  -GtkScrollbar-has-forward-stepper: true;
  min-width: 4px;
  border-width: 0px;
  border-right-width: 0px;
  border-left-width: 0px;
  margin-right: 0px;
  margin-left: 0px;
  padding-right: 0px;
  padding-left: 0px;
  /*background: #c0ff40;*/
}

slider {
  min-width: 2px;
  background: #c0ff40;
}

scrollbar trough {
  min-width: 2px;
  background: #222222;
}

scrollbar button {
  min-width: 2px;
}

@import 'colors.css';

Note that weird caching behaviour occurs; I just fattened the scrollbars by increasing min-width to 8 and restarting Thunderbird, but resetting it to 4 had no effect. After logging out and in, some of the scrollbars were still fat. But with moving around into mail sub-folders the fat scrollbar became thin.

Something I don't understand happened to scrollbars in firefox. I used the "Custom Scrollbars" extension to make the scrollbar narrower but more visible*, but one day the scrollbars became too narrow, maybe only 2 or three pixels wide. However, in the preferences for the extension I changed "default" to "thin" and they widened to 6 pixels, close to the 7 I use in Qt apps using qtcurve.

*In windows 10 scrollbars are far too wide but even so I found the thumb very difficult to see, 68% grey on a 52% grey track. What? Unusable.
