[vbox-dev] Synchronizing access to the framebuffer in VirtualBox 5

[Rūdolfs Bundulis]

Hi,

after transferring my custom frontend code to VirtualBox 5 I started to
notice small artifacts in the video stream - I assume since there are no
more Lock() and Unlock() methods I may be reading the pixels while another
update is actually in progress. Is there any mechanism to implement a
syncrhonized access to the framebuffer (using something internal from vbox
dlls is fine for me, I am already dynamically loading them to enable OpenGL
redirection).

Best Regards,
Rudolfs Bundulis
