I follow your reasoning and I agree that that certainly seems to be what might
be expected.  But, on the basis that 24bpp is unaligned and 32 bpp is aligned,
empirical evidence says that for some H/W / S/W combinations it just doesn't
seem to work like that: 24bpp works, 32bpp doesn't.

Looking at the duplicate bugs there are multiple reports of this problem
involving four other apps - and from memory I've seen at least one other report
on the Ubuntu forums for a further app.

Given that there's empirical evidence that there really is a problem with
setting the depth to 24, does the solution I outlined, enabling an override via
the registry, seem a likely solution?
