+# A test for a bug found by GraphicsFuzz.
+
+# Short description: A fragment shader with two loops and some matrices
+
+# The test passes because the fragment shader always writes red; the loops do nothing.
+# The second loop condition is always false.

+SHADER vertex variant_vertex_shader PASSTHROUGH

+# layout(set = 0, binding = 0) uniform buf0
