Hi:
I use hardware acceleration in directfb-1.6-0. The directfb-examples are
running ok now. But one of my qt 5 launcher test case have problems.
I found the problem is because of different buffer pools. My hardware
support FILLRECT. The test case first call
IDirectFBSurface_Lock to allocate a dst-buffer by function
localAllocateBuffer which is unphysical continuous, then do fillrect on the
dst-buffer,
the function dfb_surface_allocation_update allocate a new physical
continuous buffer and free the dst-buffer.
After fillrect , my test case continue to draw cursor and want to do alpha
blend with the dst-buffer. But the
dst-buffer is not exist now , then the segment faults happen. How can I
resolve this problem?
Best Regards
