compiz memory leak

[Александр]

1. Looked at task Manager, I saw the memory usage of the application compiz 2.2 GB, CPU time of 26 hours, with uptime
09:45:58 up 1 day, 18:20, 1 user, load average: 1,29, of 1.23, 0,92
2. Expect to see less гuptime and less memory consumption.
3. When the computer is idle consider the application download too large, I propose to draw attention to it.

2. Ожидал увидеть меньший гuptime и меньшее потребление памяти.» на английском:
3. При простое компьютера считаю загрузку приложения слишком большим, предлагаю обратить на это внимание.
