Image stacked on y-axis & rendering skipped on even coordinates

[drdeaton]

What I mean is the example shown at https://goo.gl/Khpy8y. What causes these 2 strange bugs and how can I fix them? Just to be clear, the image rendered is 64x64, although the part with the pointer is only 16x16.

I guess it's related to this: #41

It is not. #41 was about it hanging (which I fixed by making the image larger), so is the issue you can see with the mouse icon on tje screenshot just due to something wrong on my end or is the software bugged? To be clear, that screenshot came from a 2DS, not Citra, which is known for graphical glitches.
