-Subject: [PATCH] MGS-1236 : [imx6qp/imx6dl] First frame distored when some
- wayland apps run continuously using g2d
-
-gco2D_SetSource was missing when using the blit operations and
-hence causing the issue.
-
-If the weston started without weston.ini, animations will be disabled,
-for xwayland the weston.ini need to be included and hence the error
-was shown.
-
-Also removing util functions reusing from libGAL.so
