[Feature request] automatically switch to 1x scale during fmv cutscenes.

[Terabyte88]

So during a pre rendered fmv sequences sometimes there will be lines across the scene as a result upscaling. Now PCSX2 has a feature that turns upscaling off when an fmv plays to solve the problem, and I was wondering if PPSSPP could implement a similar feature. Maybe someone on the dev team could get in contact with the dev team of PCSX2 and ask them how they implemented it.

Another feature that would be useful is the option to disable Postprocessing shaders during fmvs in addition to switching to 1x scale, I like the why shaders make in game graphics look but they don’t do fmvs any favors.
