Public bug reported:
The recent upgrade from MESA 17.2.8 to 18.0.5 is causing the icons of some
applications bundled with Ubuntu 16.04 to be displayed incorrectly in the
status bar. The icons are surrounded by a shadow and some colorization is
missing.
The problem can be seen on the attached picture - VLC and Electrum icons are
affected by the problem (VLC's icon is surrounded by an extra shadow and
Electrum icon is supposed to be blue but is all black), and HexChat's icon is
displayed correctly next to them.
I'm using Linux Mint MATE 18.3 (based on Ubuntu 16.04's package base),
but the problem is present on Ubuntu MATE 16.04, too. The hardware i'm
using is ThinkPad T400 with an integrated Intel graphic accelerator,
using the default intel Xorg driver.
