@DTEAM No worries, this task is still on my radar. Once I start on it I want to begin by copying your screen resolution and seeing if I can reproduce the problem on my Pi. The problem you are describing is potentially more than just an issue of the config window being too large to fit the window size on the lower res since the text spacing and size is supposed to automatically adjust based on the window size. The fact that yours is getting cut off tells me that there is some potential issue in the window re-sizing functionality.
I am planning to work on your issue once I am finished with the Hardware Shader Acceleration. I really want to get the Hardware Shader Acceleration working on the Pi as it can (at the very least) allow users to precompile shaders and potentially provide other significant performance gains.
