+Subject: [PATCH] conform: only listen to after-paint after paint
+
+The after-paint signal is emitted after painting, obviously,
+but also, maybe less obviously, also emitted after picking.
+
+The actor-shader-effect test does read-pixels, so needs to
+know when painting has actually happened, not just picking.
+
+This commit changes that test to only look for the after-paint
+signal after the paint signal.
+
+In the picking case, after-paint would follow a pick signal
+instead.
+
+Fixes Xvfb installed-tests testing.
