PRWIN9110007: StretchBlt Simulation for >8 BPP Drivers UAE

Summary:

PROBLEM ID: WIN9110007

SYMPTOMS

When Windows GDI simulates StretchBlt for drivers with more than 8

bits per pixel, the application experiences an unrecoverable

application error (UAE).

CAUSE

GDI does not allocate enough memory to properly simulate the

StretchBlt, and writes past the end of the allocated memory

segment.

STATUS

Microsoft has confirmed this to be a problem in Windows version

3.0. To avoid this problem, the video driver must support

StretchBlt, which prevents GDI from simulating it.

This problem was corrected in Windows version 3.1.
