In fix #79, a change was made in window.c concerning the size of root
background tile:
! pWin->backgroundTile = (*pScreen->CreatePixmap)(pScreen, 16, 16,
! pScreen->rootDepth);
----------------------------
! pWin->backgroundTile = (*pScreen->CreatePixmap)(pScreen, 4, 4,
! pScreen->rootDepth);
We expect this was done as a lowest common denominator type fix, in combination
with a byte ordering problem in the description of the tile pattern. (The tile
pattern declared at the top of window.c also changed.)
Unfortunately this fix causes a rather dramatic performance hit(~4x) when
drawing the root background if you are using miPaintWindow. Somewhere along
the line somebody should call QueryBestSize to determine optimum tile size to
use. This could either be in window.c OR miPaintWindow. Votes here seem to
believe that it is miPaintWindow's responsibility.
Responses??

If it wasn't for the twinkies, we'd all have gone home weeks ago.
