XFCE panel screenshot

This is clearly a regression because kernel 4.12.x worked just fine here and
all 4.13.x releases exhibit this problem.

I'm running XFCE under Fedora 27 (recently updated from 26 which also exhibited
this bug) without a compositing manager.

Upon logon XFCE panel icons are always broken in one way or another. If you
move any window above the panel then everything gets back to normal. Yet when
you run `xfce4-panel -r` glitches return.

Also this bug manifests itself in Firefox when you're scrolling. Text often
gets strange artifacts.

Here are relevant kernel messages:
