Before I go on mantis'ing stuff: all the sliders in VFB cannot be typed in anymore, only slided. Is this intentional? The exposure control becomes unusable while rendering because of the VFB lag. Didn't see such a thing in the changelog.
Also while I'm here: VFB centers the image in the mid of the screen, as if it displays maximized VFB, while the VFB is windowed and cuts of part of the image, if the VFB has been resized while IR was running before.
It only does this for a resolution lower than the one was used before resizing. I hope the text makes sense.
