Missing a nibble in last writes of debug output

I am testing a thing which needs a fairly high amount of bytes. For this reason, I'm writing some bytes to a debug output and dumping them to disk.

I've noticed however the last byte written (especially at the end of a kernel) will often get a missing nibble. The low nibble is typically correct but the high nibble is very often 0.

I have observed this in various forms and I'm very confused on the cause. Even more oddly, the very same data appears to be correct when fetched from a successive stage.

 

I'm using 14.12 Omega on Windows 7 x64 with a Radeon 7750.

 

Ever noticed a similar pattern?
