1698949 - Scrollbars in chrome windows are invisible

Status: RESOLVED FIXED

(Core :: Widget: Cocoa, defect)

Description

[Dave Townsend [:mossop]]

1. Open the History menu
2. Select Show all History
3. Resize the window such that a scrollbar is needed for the history contents.
4. Note that there is space for the scrollbar and scrolling either by click and dragging or wheel works but the scroll thumb is invisible.

Careless of me to not have tested this more thoroughly. I guess this is hidpi
only because automation has aScale = 1.0, which is why automation didn't catch
this? That's sad :(
