[Martin Stránský [:stransky] (ni? me)]

Perhaps a crash at https://searchfox.org/mozilla-central/rev/3b6958c26049c1e27b2790a43154caaba9f6dd4a/widget/gtk/GtkCompositorWidget.cpp#17 but it's hard to say where exactly as it's optimized out.

Maybe

mXDisplay = XOpenDisplay(aInitData.XDisplayString().get())

or

if (!XGetWindowAttributes(mXDisplay, mXWindow, &windowAttrs)) {

unfortunately we don't have the xlib symbol in backtrace.
