Offline Preview not working, and more

Hi there, I just downloaded Reshade for the first time. After getting familiar with it, the Offline Prewview fuction just stops rendering the image with effects enabled. It alsp fails to load preset properly as selected effects aren't showing on the preset itself in Reshade. Please help, thank you!

That, and also this other problem I posted on another thread:
It doesn't have the option to display a picture on it's native resolution. If you want to see the changes in an AA effect like SMAA, it's impossible to use it because the picture is resized and totally blurred.

I tried adjusting the window to shows the picture 1:1 in it's native resolution, which is painful but possible, but as soon as I change a setting and click Apply the Offline Preview window resizes by 1 or 2 pixels every time, I don't know why. This makes it impossible to use the Offline Preview effectively for effects like AA or others because the image is horribly blurred.
