Comment(by jng):

 Here's my observations thus far.

 The striped effect happens when your MaxRasterImageHeight and
 MaxRasterImageWidth are greater than the size of the image you are
 requesting.

 This conclusion was made through 5 tests with various serverconfig.ini
 values using your sample request.

 Test case #1:

 MaxRasterImageHeight = 2048 (default)
 MaxRasterImageWidth = 2048 (default)

 No stripes

 Test case #2:

 MaxRasterImageHeight = 3072 (default)
 MaxRasterImageWidth = 3072 (default)

 No stripes

 Test case #3:

 MaxRasterImageHeight = 4096 (default)
 MaxRasterImageWidth = 4096 (default)

 Striped effect occurs

 Test case #4:

 MaxRasterImageHeight = 4000 (default)
 MaxRasterImageWidth = 4000 (default)

 No striped effect

 Test case #5:

 MaxRasterImageHeight = 4001 (default)
 MaxRasterImageWidth = 4001 (default)

 Striped effect occurs.
