If the GL configuration is broken for some reason, then any WebKitGTK+ window will be empty if AC is enabled.
This is my the test case:
I use the nvidia propietary drivers, so by setting the path to the mesa ones I mess with my GL setup
$ export LD_LIBRARY_PATH=/usr/lib/mesa-diverted/x86_64-linux-gnu
$ glxinfo
name of display: :0.0
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
X Error of failed request: GLXBadContext
Major opcode of failed request: 155 (GLX)
Minor opcode of failed request: 6 (X_GLXIsDirect)
Serial number of failed request: 54
Current serial number in output stream: 53
Now if i run MiniBrowser I always get an empty window for any site that enables AC (even google.com)
No crash however. I don't get a coredump and the webprocess don't crashes.
If I manually opt to disable AC by doing
export WEBKIT_DISABLE_COMPOSITING_MODE=1
Then all works (no fancy animations, but it just works fine)
