+Subject: [PATCH 1/2] MGS-2343 [#ccc] XWLD: T3DStressTest_Wayland displays
+ abnormally while using G2D compositor
+
+It need add g2d_finish after repaint_region and before copy to framebuffer.
+Because if using dual dpu cores, the tasks on each core will be executed
+sequently, but it can't ensure one task splited on dual cores can be finished
+synchronously by hardware.
+
+Upstream-Status: Inappropriate [i.MX specific]
