3d frame not drawn correctly on seamless mode since 4.2.12

[wnssh]

Hello, a problem about 3d support is appeared since I upgraded to vbox 4.2.12. It always missing drawn some piece after the 3d buffer upgraded, and it can show them for a while when I drag the 3d window.

Here is my environment: host: centos 6.4 64bit guest: windows xp sp3 and windows 7 sp1 (both have this problem) involved software: any software use 3d drawn (dx to opengl or opengl) mode: only seamless mode, not affect other mode version:

host 4.2.10 guest 4.2.10 not affect host 4.2.12 guest 4.2.12 affect host 4.2.14 guest 4.2.14 affect

video card:

Nvidia GeForce 210

I compared the log and no different place, so I dont upload them. Hope someone can take a look, thanks.
