--- Comment #100 from Rafał Mużyło  ---
'win' channel shows a window with WS_CHILD, but it might just as well be a
clipping problem ('region' has a couple 0 rect regions, but those might be
legit).

Potentially of note: both testcases (from the same dev) need native d3dx9_31 -
if moved to use builtin, what follows might be a stack corruption - 'Unhandled
page fault on read access to CCCCCCCC at address ...'.
