I opened a bug for this months ago: https://bugs.scummvm.org/ticket/11948 I hope one day someone fixes it.
ScummVM is heavily reliant on volunteers, obviously. What they've managed to do is really quite a miracle. Especially with games like Blade Runner where they've added lost scenes and puzzles, etc. But yeah, when you're a die-hard like us, it can be frustrating that things aren't pixel perfect -- even though they have a continuous stream of pull requests, there's endless work to be done! (I have daydreams of finally committing time to the project, becoming an amazing coder, and fixing all the niggling issues that bother me.)
I managed to persuade one amazing person to fix the clocktower bug in the CD-ROM version of SOMI. Turns out the CD-ROM version of the game has a ton of weird bugs in it, as if a developer tried to bug fix it by reading the code. That particular one has bugged me for decades. The dev fixed a few more things like this, too:
https://github.com/scummvm/scummvm/pull/3239
https://github.com/scummvm/scummvm/pull/3252
https://github.com/scummvm/scummvm/pull/3253
https://github.com/scummvm/scummvm/pull/3211
They're a damn hero, I tell ya!
