[meta-freescale] [PATCH v3 1/5] weston: T3DStressTest_Wayland displays abnormally while using G2D compositor

[Tom Hochstein]

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]
