[Qemu-devel] [Bug 665743] [NEW] Cocoa video corruption when guest uses RGB565 mode

[Todd Jones]

Public bug reported:

The cocoa video driver doesn't currently support when the guest uses
RGB565 or HighColor mode resulting in corrupted video.  The initial
graphics screen of recent Ubuntu installs is an example.  The attached
patch against 0.13.0-release seems to fix the problem by introducing an
indirect data provider that translates from RGB565 to RGB888, a mode
that core graphics supports.

Can you still reproduce this problem with the latest version of QEMU? If
so, could you please rebase your patch to the latest git version and
send it to the mailing list (see http://qemu-
project.org/Contribute/SubmitAPatch for details)? Sorry, we do not take
patches from the bugtracker, they always have got to be discussed on the
qemu-devel mailing list first.
