Hongna is the true reporter.

This bug only occur when 64b target running on 32b host. The root cause is that target pass 64b data to host, but host treat them as 32b data, so wrong data happen.

We need make the type of data buffer in qemu host same as target. Patch will be out soon.

The RGB error is a dupe of bug 2309 which has now been fixed in oe-core and poky master as of:
