Description
It appears to be a problem with the aspect ratio and whenever the filter goes into one of the snes' hi-res modes, there's more about it here https://forums.libretro.com/t/possible-bug-with-blarggs-filters-in-the-snes9x-core/32746/6

To display the video output proportionately an accurately
Actual behavior
Steps to reproduce the bug
Not entirely sure
- Select your bsnes core with game as you normally would
- Apply your shader which is fine
- Apply the BLARGG NTSC RGB CPU filter under video settings
Bisect Results
Occasionally the aspect ratio goes too slim in some games like the image above, on DOOM it's the intermission screens and startup screens.

Research direction
Start at the BLARGG NTSC RGB CPU filter under RetroArch's video settings and reproduce the issue with a bsnes or other SNES core, including a hi-res mode such as the one described for DOOM. Compare the output aspect ratio with and without the filter and consult the linked forum discussion. Done means SNES video output remains proportionate and accurate in affected screens.
