It doesn't seem that this has been reported anywhere. Hook (USA).sfc seems to have some serious artifact issues in (RPi 3) lr-Snes9x 2010 so I'll be loading it with Snes9x 2005 for now, with inferior sound.
I tried several versions of Snes9x for Windows (including builds from around 2010) and there isn't such an issue. I have also submitted this on retropie.org (just in case someone notices first).
This happens if invalid vram access is allowed. S9x2010 has it set to disabled, but one of the speed optimizations causes it to not take effect completely. I'll see if I can commit a fix.
