Hello,
I saw your example and I think that is not error in unDelphiX last version.
You can draw set of images (74 clips 72x72px) from image size 5328x72px.
I try it and the is problem with physical size of texture (some adapteurs support 2048x2048px only). Texture is shrinked to physical size (or other me unknown method) but unDelphiX recount size on bitmap size.
I do glue your images to raster 9x9img and set of limit images (because emty images created) and it works very fine. I don't know instant solution now, but I try in prepared version 1.08 better test for large images with supported texture size. I use your demo for future tests
