I got compiz to work with Ubuntu trusty. The workspace switcher plugin works very well, however with the desktop cube plugin i get strange distortions while the cube is shown:

Looks like the 3D / texture logic is failing or something. (Once the desktop switch is finished everything's back to normal).
Has anyone seen this before / any idea how to fix this ?
For reference:
- graphics card is an intel integrated card, previous ubuntu versions had no problem with it. (Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics card)
- this is compiz
0.9.11.2 (1:0.9.11.2+14.04.20140714-0ubuntu1) - ccsm profile (without default values)

I had similar problems with an Acer D270. The graphics were laggy and unacceptable. My solution was to switch to a lighter weight distro without 3d effects. Both Lubuntu and Xubuntu will work well with your system.
1After reviewing your ccsm settings I think what you are missing is:
[cubeaddon] s0_deformation=0
Open Compiz Config Settings manager. You will be warned to use caution. Click OK.
Enter deform in the filter box then click the button shown below:
Set Deformation to none. My settings are shown below. I'm not positive the other Cube Reflection and Deformation settings relate to your specific issue however if simply changing deformation to none doesn't do the trick you can try them.
Finally found what's causing the issue:
- Open CompizConfig Settings Manager
- Select OpenGL plugin
- Disable "Vertex buffer object" option:
Render all graphics primitives using vertex buffer objects (GL_ARB_vertex_buffer_object), if supported by the driver.
Pros: This provides higher graphics performance for some drivers.
Cons: This is a new feature and may cause graphical problems.
Note: This feature is always on in OpenGL|ES builds such as ARM platforms
Now textures display alright !
Looks like intel driver is not ready for this yet.
Also came across this thread:
If you care about performance it might be worth playing with the other OpenGL settings...
