Instead of "complaining" of Dolphin rendering 30 Hz games on 60 Hz mode, I would give eternal thanks to God for that thing happening.
For instance, not all Zelda games run at 30 FPS all the time. 30 Hz games are both rendered in 30 Hz and 60 Hz mode (30 FPS in gameplay, 60 FPS in cutscenes/cinematics). Same happens on some Mario games (PAL region specifically, using SMS and LM: 25/30 FPS in gameplay, 50 Hz in cutscenes/cinematics).
Don´t want image fragmentation/tearing? Don´t use V-Sync at all and save money by not buying that things.
