Youtube play issue on Chrome!!(while 3D accelerated!!)

[MounTainLion]

Someone please explain about why can't I play Youtube on Chrome Browser on Windows 8.1!!!

My host machine is Linux, and I installed Window8.1 as VM.

first time, i didnt accelerate 2D and 3D, and didt install "Virtual Box guest additions", and i could see Youtube video cleary.
but after i installed guest additions and enabled 2D and 3D, i can't see videos, just black screen.(on Windows Internet exploere, No problem!)
seems like there is some kind of discord between "3D acceleration" and "chrome"(if i disable 3D acceleration, i can see video again!)

Also i could feel windows internet explorer is little bit slower than usual when i play Youtube video.

I hope someone knows about this problem and can fix it!

3D Acceleration is still experimental, especially on very recent guests like Windows 8.1, so there is no guarantee it works.

Can you tell me when Virtualbox going to fix these error? is it on the plan?

The devs don't share their schedule, so your guess is as good as mine.

Google Chrome plays YouTube videos just fine in my Windows 8.1 guest. 3D and 2D enabled. Mac host.
