SUMMARY
STEPS TO REPRODUCE
1.

3.
OBSERVED RESULT
The image data that was loaded seems to be four pointers (I determined these
using the color picker, so take them with a grain of salt):
f0 72 3f 1e 22 7f 00 00
f0 72 3f 1e 22 7f 00 00
d0 6e 1b 4c 1f 56 00 00
d0 6e 1b 4c 1f 56 00 00
The rest of the image was null bytes.
This is a dump of the memory at those locations:
