Everything worked fine in 12.04 TLS, now I can't view movies properly because of distortions (both online video and files from my drive), compiz uses about 40% of CPU. Any help?

This might not be that visible when using high-end gpus, but should be clearly visible when using compiz on llvmpipe and to some-extent invalidates the approach of using compiz on top of llvmpipe as a fallback when no GPU is available: How to reproduce: 1) Use the unity-3d desktop in Ubuntu 14.04 on top of a non-accelerating Xorg driver like "modesetting". Move windows around. Note peak and average cpu-usage. How to verify compiz is the culprit: 1) copy /usr/bin/compiz from a Ubuntu 12.04 installation. Drop it in as /usr/bin/compiz on 14.04. Reboot. Perform the same window movement. CPU-usage should be substantially lower. This problem also affects VMs running on VMware ESX with a software- rendering GPU. Window movement becomes sluggish, which suggests that even with GPUs, compiz has increased the number of operations required to move windows.
