Since the .designer.cs file is just normal everyday code, you can combine the two files (and trim out bits unrelated to your problem description) and post the results. Or, even better yet, there's nothing stopping you from creating a form from the ground up like's been shown in a couple of examples now.

indeed, if there is even one pixel of difference in size between the two bitmaps sizes, a "BitBlt" (tile zoom to fit the space, GDI+ may have another name for that function) may screw the whole one-to-one representation and that is where a blur or other inconsistencies could easily show up. A textured brush would take your available bit map and would not try to resize it in any way, but rather repeat it (tile it) or crop it as required, *if* the problem is one linked to the area size. If it is a problem linked to a poor driver or of monitor resolution, though, it *may* not help, indeed.
