Hi,

I suspect its an alignment issue, since GreCreateBitmap requires 32bit alignment, while CreateBitmap uses 16 bit alignment.
So changing

+    static const WORD wPattern55AA[] = { 0x5555, 0xaaaa, 0x5555, 0xaaaa, 
0x5555, 0xaaaa, 0x5555, 0xaaaa };

to

+    static const DWORD wPattern55AA[] = { 0x5555, 0xaaaa, 0x5555, 0xaaaa, 
0x5555, 0xaaaa, 0x5555, 0xaaaa };

Should do the trick.

Log:
[Win32k|User32]
- Move creation of the scrollbar Gray brush from user32 to win32k.
- Noticed a color and pattern (patchy white pattern) difference when using 
GreCreateBitmap and it did not work the same as the main function. Correcting 
this fixed the Gray brush. Someone from YAROTOWS needs to look into this.
