Proper 1366x768 support
I would like to say that this version of the engine is by far the best so far. One small problem lingers - no proper 1366x768 support. I can run it at this resolution, however, it tends to stretch, rather than fit, unlike GZDoom. So everything looks slightly squashed. If this, and some minor resolution change bugs can be fixed, this port would even greater than it already is now.

By default all are set to use an intelligent automatic stretching when the window's aspect ratio is relatively close to that of the original game. In your 1366x768 case, this stretching should be disabled if you want aspect correct scaling (note that windowing will be applied).
