SUMMARY Under the new logic of GTK settings carryover where things aren't configurable independently for GTK, if I select an application style like "breeze" and configure it to show arrows on scrollbars, it will not show arrows on scrollbars of GTK apps. STEPS TO REPRODUCE 1. Go to System Settings -> Appearance -> Global Theme -> Application Style -> select "Breeze". 2. Click the edit button in the breeze rectangle. 3. Go to "scrollbars". 4. Set both "Top arrow button type" and "Bottom arrow button type" to something **other** than "No buttons". 5. Apply the settings. Optionally, restart computer at this point. 6. Launch some GTK app like "nemo" or "evolution". Put it into a situation in which it will need a scrollbar - for example, by browsing a folder with many files, or by having many emails to browse. OBSERVED RESULT Scrollbars don't have arrows. EXPECTED RESULT Scrollbars should have arrows.

Do you know if this worked in the past? And in the present, does GTK even support these settings with the same level of granularity that we do? i.e. can you manually make the GTK apps' scrollbars have the same number and position of arrows that you can with Qt apps' scrollbars?

I don't know if Breeze applied those settings to QT in the past. But back then, it was possible to choose the GTK application style and set something other than breeze. Don't remember if the arrows were applied from another theme either. I'm not familiar with other linux DEs so don't know how to configure that sort of thing either.
The problem is that as far as I can tell, GTK doesn't natively offer this feature. We would have to hack it in using CSS in our breeze-gtk theme. It might be feasible, or it might not be.
