Android-x86 4.4-r1 - display rendered improperly/extremely slow

[TheReduxPL]

Hello.
I'm trying out Android-x86 4.4-r1 on my PC. I have Ubuntu and Windows installed, now I installed Android-x86 on a separate partition and added it to Ubuntu's GRUB. It seems to start fine but I got a problem.
When I start Android with the "xforcevesa" parameter, everything on my screen is heavily distorted but mouse seems to be perfectly responsive. When I boot it without "xforcevesa", screen looks fine but everything is lagging - OS boots noticably longer and it takes 2 seconds for my mouse to move - basically unusable. Any ideas how to fix it?
Here's the photo of distortion (too big for an attachment): http://i.imgur.com/aFziAzg.jpg

Intel Core i5-3350P
Radeon HD7770
10GB RAM
1680x1050 screen

PS: Sorry if I accidentally published this post twice. I tried to do it once and it didn't appear in the thread list, not sure of this Google Groups thingy is moderated or not.

Hi, try to use your intel igp instead of Radeon 7770. This model is not yet suppoted

Aww, I don't have any IGP in my PC :( Some CPUs come without the integrated graphics, like mine.
Do you know when the support for that GPU will be added?

Some guys are working it out (I also try to help).
I don't have a precise date. Can only answer "when is ready" so far :)

Ps: We have to enable llvm radeon specific functions and maybe upgrade Kernel to be able to make it work.
