Able to reproduce the issue on Ubuntu 14.04 using 54.0.2804.0.
Its working fine on Mac 10.11.5.

Note : Switch theme to gtk+theme/classic to better reproduce it.

Thanks for filing this, definitely the right CL identified, something to do with the translucent widgets on Linux.

[md] Fixes tooltips regression on Linux that should not have changed

I have tried making rounded corners work on Linux but so far haven't
succeeded. I can make the non-opaque background work using
Widget::SetOpacity and ui::Layer::SetFillsBoundsOpaquely but the native
widget on Linux still paints around the rounded corners.
Widget::SetShape doesn't use antialiasing so using that to achieve
rounded corners appears crude.
There is some work to make transparency work better on Linux
https://codereview.chromium.org/2124633002 so I haven't pursued this
further.
