After looking again into th sources of "graywin" I have to clearify something.
The graywin application draws its background at application start, at a resize event and at a exposure event ... that
means that "loosing of the rectangles" is a designed behavior iin the context of the expected events!
SDL 1.2.9 creates the resize and exposure events under QNX 6.4.1 ... but not SDL 1.2.13 !
The exposure event is also missing under QNX 6.2.3 and with SDL 1.2.9 and SDL 1.2.13 !
That means only SDL 1.2.9 is fully working under QNX 6.4.x after the modification of the handling of the window
background !!
SDL 1.2.13 has problems with the event handling (the exposure event is missing) and there are strange effects with the
blitting. At start of graywin you can see sometimes a corrupted window contents. I saw also that the testpalette app was
failing to create a correct window contents.
At the end I have go back to SDL 1.2.9 ... sorry about that :)
So I don't belief that your implementation of the blit handling is in general a great mess ... its is working perfectly
with SDL 1.2.9.
