I have a really annoying issue that I cannot explain.
My bokeh server application is a thing of pure beauty on chrome (linux, windows and android), MS explorer/edge (win) and firefox (win / linux / android).
Unfortunately, my colleague who uses safari on IOS is unable to appreciate it in its full splendor, as one of the plots (thick, colored line segments) renders in two shades of grey on his mac! The other plots on the same page (shape glyphs) render in color.
I have no idea what would cause this, has anyone seen this behavior before?
