+Subject: [PATCH] fix client->gfx_state initialisation
+
+Shortly before the DirectFB 1.7.7 release, an optimisation was added
+to CoreGraphicsStateClient_Init() to avoid creating an extended
+Graphics State object if it will not later be required:
+
+  4d422fb Client: Create extended Graphics State object when needed for later usage
+
+Unfortunately the client->gfx_state variable used to track the
+extended Graphics State object is not initialised, which can lead to
+crashes etc due to creation of the Graphics State object erroneously
+being skipped.
+
+Upstream-Status: Pending
