Default unopened tile appearance is painful: Rounded square corners create Hermann grid illusion

Description
Created attachment 327479 Screenshot exhibiting the Hermann grid illusion
An unopened tile is displayed as a dark gray rounded-corner rectangle on a light gray (gtk+3 theme-dependent?) background.
When arranged in a grid, they induce the optical illusion known as Hermann grid illusion. Dark dots seem to appear at the intersections. This is visually jarring. Changing to the classic theme does not change the unopened tile appearance.
