(Core :: Graphics, defect, P3)

Description

[Paul Adenot (:padenot)]

STR:
- Run `xvfb-run mach mochitest --flavor=plain --disable-e10s  dom/media/webaudio/test/` (same result in e10s)

Expected:
- it works, we can run mochitest with xvfb

Actual result:
- Assertion failure: mFormat != gfx::SurfaceFormat::UNKNOWN (Could not find SurfaceFormat for visual!), at /home/padenot/src/trees/mozilla-central/widget/gtk/WindowSurfaceX11.cpp:26

You need to force it to 24-bit color like this:

  xvfb-run -a -s '-screen 0 640x480x24' ./mach mochitest

I think someone on the gfx team knows about this, but not sure if there is another bug on file.

Graphics, even though the code is under widget/gtk.
