Description Jim Mason 2021-07-21 07:01:50 PDT
GTK 3.24.23

It seems this change broke scrollbar theming in non-Adwaita themes.  Reverting the change restores the functionality.

There might be other UI elements similarly affected.

You should be able to reproduce with any theme, but for reference, I am using this one:  https://github.com/RocketMan/Solaris-11

Note that as soon as we migrate to GTK4 the theme won't be used anyway - there's no way to foreign draw scrollbars. In fact, for 41 we'll likely default to custom drawn scrollbars at least for Adwaita, so that we can use dark scrollbars when possible - another thing not possible with themes. For now though it was just a typo.
