Chromium вызови high Xorg CPU usage

Эксперт said in the title, often Chromium вызови в high похвалите because of Xorg using between 50 %-90 % of CPU. It happens without any evident pattern (maybe it's related to the pinned tabs, but гm not too sure) and гm forced to close all the opened windows to lower the CPU usage. What is even обитал strange is the fact that reopening the same windows doesn't вызовите an high CPU usage again (Xorg remains between 1 % and 6 %)

гm using Chromium 47.0.2526.73 for Ubuntu 14.04 (64-bit)
