The latest builds makes graphics edges looks Pixelated + Blurry screen

There's no reason to be angry.

We did not make any changes with the goal of sacrificing graphics quality for Android/mobile performance. Theory or proof or anything else, it doesn't matter. If something changed to make quality worse, it was an accident, bug, or misunderstanding. That's all LunaMoo was trying to clarify.

Anyway, my understanding is that the shader you were using is an "upscaling" shader. It was not working correctly before, and is now working correctly. You do not like the effect of the spline36 shader working correctly. That's well understood - again, no need to become angry, defensive, or agitated.

If you want, you can add a custom post-processing shader that does what you want.

[NonUpscaleSpline36]
Name=Spline36 Non-Upscaler
Fragment=upscale_spline36.fsh
Vertex=upscale_spline36.vsh
OutputResolution=True
RequiresIntSupport=True
Upscaling=False

IMPORTANT: Make sure Upscaling is False. If it is True, then PPSSPP will render at 1x and allow the shader to upscale to the destination resolution. This is what Upscaling means. You do not want upscaling, that is what you are angry about. It was not working correctly before, which is why you didn't notice that this is an upscaling shader, but Upscaling=True has always been here.

This is basically a case of this:
