The fix for RT-10840 resolved the major issue where the content was always being stretched or scaled when the window was being resized, instead of being drawn at a fixed size and just seeing more or less of the window. Additionally, on D3D, code was added to draw the correct content size rather than resizing the content to fill the entire window.

Resizing now works correctly on Windows, but there is still a short lag on Mac where the content size will "jump" slightly and then snap back to the correct size, indicating that a similar solution will be needed for OpenGL as was done for D3D.
