--- Comment #10 from Carlos Garcia Campos <cgarcia at igalia.com> ---
When closing AcceleratedBackingStoreX11::update() is called with a null LayerTreeContext, so the function should always return from the !pixmap early return. That's why I didn't add the trapper at the bottom. I don't understand why it happens, but I guess it's safe to trap xerrors in that case too.
