Right, message logs of 20041201 (which worked ok) and 20050111 (which
doesn't work) are at:

Load into your favourite visual diff tool and compare :-)

These are logs just from the point where I hit the OK button in each
build in order for PSP to create a drawing canvas; as soon as the canvas
window was visible I hit ctrl-C from the controlling terminal (to avoid
lots of shutdown message trace in the logs). So in theory, it's just the
relevant bit...

... I've also filtered out WM_MDIGETACTIVE, WM_GETDLGCODE and
WM_IDLEUPDATECMDUI as they ate up a lot of log space and didn't seem to
related to this redraw problem.

All versions after and including wine 20050111 have the redraw bug, but
I just picked the next version after the working 20041201 as diff
results are more likely to show up what the problem is.

Oh, I filtered out all WM_* events and compared them too; there's no
"missing" WM_* events from the later code, although my simple checks
there wouldn't detect if the order in which things happened changed.

Note that the diff output is very similar, apart from a few places
where the order of things seems to get swapped around a little (next
challenge for me is to figure out which of these messages are relevant
and what they mean!).

should be with the checkered background:
