Thanks for taking a look. I added a conversion to test_LockBits, but to me it looks that neither bits are read from nor wrote back into the bitmap. Is this somewhere near what you had in mind? Yep, this explains native's behavior pretty well: no read/write access is apparently a valid (though seemingly useless) configuration, and the optimization that points callers directly to the bitmap's backing memory effectively converts that to read+write. And that lines up with the fix.
