The following example gives a blank screen with the PF_RGBA8888 format and using the D3D7Max2DDriver(), using PF_BGRA8888 or GLMax2DDriver() works as expected.
'SetGraphicsDriver GLMax2DDriver()
SetGraphicsDriver D3D7Max2DDriver()
Const Pixfmt=PF_RGBA8888 ' doesn't work in D3D7Max2DDriver()
'Const Pixfmt=PF_BGRA8888
Graphics 640, 480,32
Global pmap:TPixmap = CreatePixmap(100, 100, pixfmt)
For x = 0 To 99
For y = 0 To 99
WritePixel(pmap, x, y, $ff0080ff)
Next
Next
DrawPixmap pmap, 0, 0
Flip
WaitKey
End
