The diagnostics added in 12583e9 paid off!
BitBlt returned false but did not set the last error. GdiFlush(): True. Last error after GdiFlush: -559038737
The fact that BitBlt did not set the last error to something other than -559038737 (0xdeadbeef
) when returning false
means that we will have to set it to zero before calling in order to know whether it is returning false
because of failure or whether it is returning false
because the operation was batched.

Reverted the additional diagnostics now that all outstanding questions have a satisfactory answer: 03e6c93
